"Derek Bailey (29 January 1930 - 25 December 2005) was an English avant-garde guitarist and leading figure in the free improvisation movement.

Bailey was born in Sheffield, England. A third-generation musician, he began playing the guitar at the age of ten, initially studying music with his teacher and Sheffield City organist C. H. C. Biltcliffe, an experience that he did not enjoy, and guitar with his uncle George Wing and John Duarte. As an adult he worked as a guitarist and session musician in clubs, radio, dance hall bands, and so on, playing with many performers including Morecambe and Wise, Gracie Fields, Bob Monkhouse and Kathy Kirby, and on television programs such as Opportunity Knocks. Bailey's earliest foray into 'what could be called free improvised music' was in 1953 with two other guitarists in their shared flat in Glasgow. He was also part of a Sheffield-based trio founded in 1963 with Tony Oxley and Gavin Bryars called "Joseph Holbrooke" (named after the composer, whose work they never actually played). Although originally performing relatively "conventional" modal, harmonic jazz this group became increasingly free in direction.

Bailey moved to London in 1966, frequenting the Little Theatre Club run by drummer John Stevens. Here he met many other like-minded musicians, such as saxophonist Evan Parker, trumpet player Kenny Wheeler and double bass player Dave Holland. These players often collaborated under the umbrella name of the Spontaneous Music Ensemble, recording the seminal album Karyobin for Island Records in 1968. In this year Bailey also formed the Music Improvisation Company with Parker, percussionist Jamie Muir and Hugh Davies on homemade electronics, a project that continued until 1971. He was also a member of the Jazz Composer's Orchestra and Iskra 1903, a trio with double-bass player Barry Guy and tromboneist Paul Rutherford that was named after a newspaper published by the Russian revolutionary Vladimir Lenin.

In 1970, Bailey founded the record label Incus with Tony Oxley, Evan Parker and Michael Walters. It proved influential as the first musician-owned independent label in the UK. Oxley and Walters left early on; Parker and Bailey continued as co-directors until the mid-1980s, when friction between the men led to Parker's departure. Bailey continued the label with his partner Karen Brookman until his death in 2005[citation needed].

Along with a number of other musicians, Bailey was a co-founder of Musics magazine in 1975. This was described as "an impromental experivisation arts magazine" and circulated through a network of like-minded record shops, arguably becoming one of the most significant jazz publications of the second half of the 1970s, and instrumental in the foundation of the London Musicians Collective.

1976 saw Bailey instigate Company, an ever-changing collection of like-minded improvisors, which at various times has included Anthony Braxton, Tristan Honsinger, Misha Mengelberg, Lol Coxhill, Fred Frith, Steve Beresford, Steve Lacy, Johnny Dyani, Leo Smith, Han Bennink, Eugene Chadbourne, Henry Kaiser, John Zorn, Buckethead and many others. Company Week, an annual week-long free improvisational festival organised by Bailey, ran until 1994.

In 1980, he wrote the book Improvisation: Its Nature and Practice. This was adapted by UK's Channel 4 into a four-part TV series in the early '90s, edited and narrated by Bailey.

Bailey died in London on Christmas Day, 2005. He had been suffering from motor neurone disease."

"Julie Tippetts (born Julie Driscoll, 8 June 1947) is an English singer and actress, known for her 1960s versions of Bob Dylan and Rick Danko's "This Wheel's on Fire", and Donovan's "Season of the Witch", both with Brian Auger and The Trinity. Along with The Trinity, she was featured prominently in the 1969 television special 33 1/3 Revolutions Per Monkee, singing "I'm a Believer" in a soul style with Micky Dolenz. She and Auger had previously worked in Steampacket, with Long John Baldry and Rod Stewart.

"This Wheel's on Fire" reached number five in the United Kingdom in June 1968. With distortion, the imagery of the title and the group's dress and performance, this version came to represent the psychedelic era in British rock music. Driscoll recorded the song again in the early 1990s with Adrian Edmondson as the theme to the BBC comedy series Absolutely Fabulous, the main characters of which are throwbacks to that era.

Since the 1970s, Driscoll has concentrated on experimental vocal music. She married jazz musician Keith Tippett and collaborated with him and now uses the name Julie Tippetts, adopting the original spelling of her husband's surname. She took in Keith Tippett's big band Centipede and in 1974 sang in Robert Wyatt's Theatre Royal Drury Lane concert. She released a solo album, Sunset Glow in 1975; and was lead vocalist on Carla Bley's album Tropic Appetites and also in John Wolf Brennan's "HeXtet".

Later in the 1970s, she toured with her own band and recorded and performed as one of the vocal quartet Voice, with Maggie Nichols, Phil Minton, and Brian Eley.

In the early 1980s, Julie Tippetts was a guest vocalist on an early single by pop-jazz band Working Week, on the song "Storm of Light", which brought them to the attention of a wider audience."

"Though the point of reference for many remains the iconic band Henry Cow, which he co-founded in 1968 and which broke up more than 30 years ago, Fred Frith has never really stood still for an instant.

In bands such as Art Bears, Massacre, Skeleton Crew, Keep the Dog, Tense Serenity, the Fred Frith Guitar Quartet, Eye to Ear, and most recently Cosa Brava, he has always held true to his roots in rock and folk music, while exploring influences that range from the literary works of Eduardo Galeano to the art installations of Cornelia Parker.

The release of the seminal Guitar Solos in 1974 enabled him to simultaneously carve out a place for himself in the international improvised music scene, not only as an acclaimed solo performer but in the company of artists as diverse as Han Bennink, Chris Cutler, Jean-Pierre Drouet, Evelyn Glennie, Ikue Mori, Louis Sclavis, Stevie Wishart, Wu Fei, Camel Zekri, John Zorn, and scores of others.

He has also developed a personal compositional language in works written for Arditti Quartet, Asko Ensemble, Bang on a Can All-Stars, Ensemble Modern, Concerto Köln, and ROVA Sax Quartet, for example. Fred has been active as a composer for dance since the early 1980s, working with choreographers Bebe Miller, François Verret, and especially long-time collaborator and friend Amanda Miller, with whom he has created a compelling body of work over the last twenty years.

His film soundtracks (for award-winning films like Thomas Riedelsheimer's Rivers and Tides and Touch the Sound, Peter Mettler's Gambling, Gods, and LSD, and Deborah Kaufman and Alan Snitow's Thirst, to name a few) won him a lifetime achievement award from Prague's "Music on Film, Film on Music" Festival (MOFFOM) in 2007. The following year he received Italy's Demetrio Stratos Prize (previously given to Diamanda Galas and Meredith Monk) for his life's work in experimental music, and in 2010 was awarded an honorary doctorate from the University of Huddersfield in his home county of Yorkshire.

Fred currently teaches in the Music Department at Mills College in Oakland, California (renowned for over fifty years as the epicenter of the American experimental tradition), and in the Musik Akademie in Basel, Switzerland."

"Akio Suzuki is known as a pioneer of sound art, but the breadth of his activities and the form of his works far exceeds the normal boundaries of sound art. It is perhaps more as a "quester after sound and space" that he has received the most attention from artists in many fields.Suzuki's journey as an artist began in 1963 with a performance at Nagoya station, in which he threw a bucket full of junk down a staircase. The inspiration behind this performance - the idea that if one were to hurl an object down a well-balanced stairway, a pleasant rhythm might be the result - took the desire to "listen" as its subject. That desire to hear, to listen has remained the one constant in Suzuki's stance as an artist.

During the sixties, Suzuki's sense of playfulness led him to undertake a series of Self-Study Events, where he explored the processes of "throwing" and "following", taking the natural world as his collaborator. The experiences he gained in these events led him in the seventies to invent an echo instrument he named Analapos. The instrument's structure resembles that of two mirrors facing each other, reflecting into infinity. As an extension of the principles underlying Analapos, Suzuki constructed the Hinatabokko no kukan (Space in the Sun) in 1988. This space consists of two huge parallel walls, in between which the artist can sit all day and purify his hearing by listening to the reflected sounds of nature. This space leads the artist to discover a new method of listening. Suzuki himself comments, "Sound, which had been conceptually imprisoned in various spaces, is freed to circle the world."

From the late seventies and through the eighties, Suzuki also developed a form of performance he refers to as Conceptual Soundwork. Applying a number of self-imposed, simple and austere rules, he uses objects close at hand in a mode of "intellectual play". While these events do on the one hand express a critique of meaningless improvised performance, at the same time Suzuki is constantly aware of the audience's process of listening and he attempts to create contemporaneous connections with the site of performance. It was around this time that Suzuki began to travel frequently to the US and Europe, and his performances at leading music festivals, Festival d'Automne (Paris, 1978) and Documenta 8 (Kassel, 1987) were rapturously received.

As sound art enjoyed a period of prosperity in the nineties, Suzuki was given the chance to create many installations, particularly in Berlin. Worthy of special note were his soundless installations, such as Otodate (Echo point, 1996) in Berlin, Enghien-les-Bains (since 1997, http://www.insitu-enghien.org/) and Strasbourg; Hana (Flower, 1997) at the Stadtgalarie Saarbrucken; and Pyramid (1999) which involved people excavating sounds. These soundless pieces were not designed to critique the old perceptual theories of music, rather they questioned the very location of music. Through their encounter with these works, the past experiences and memories of viewers were reconstructed as new experiences. This process was fundamental to the action of "listening" to the works.

"A West Coast experimentalist who is an innovative performer on the harp as well as a composer embracing unusual challenges, Anne LeBaron's compositions have been performed around the globe. Venues in Italy, Mexico, Sydney, Vienna, Sweden, Kazakhstan, New York, Los Angeles, and elsewhere have programmed her works for chamber groups, opera, cantatas, and presented her as a performer. Her operas celebrate legendary figures such as Pope Joan, Eurydice, Marie Laveau, the American Housewife, and Aldous Huxley. Her current opera-in-progress, Huxley's Last Trip, (formerly LSD: The Opera) was awarded one of the first Discovery Grants from Opera America. The orchestra includes instruments built by American composer and inventor Harry Partch. Excerpts have been performed at three LA venues: at the Wallis Annenberg Theater in Beverly Hills, at the MAK Center for Art and Architecture at the Schindler House, and at the REDCAT in downtown Los Angeles.

LeBaron was recently awarded a Copland House Residency in New York, a Djerassi Program residency in Santa Cruz, and a residency at the Corporation of Yaddo in Saratoga Springs. Radiant Depth Unfolded: Settings of Rumi, commissioned by The Sorel Organization and SongFest, premiered in Zipper Hall at the Colburn School in Los Angeles. The Los Angeles Library Foundation commissioned her to compose a work inspired by the Oxford English Dictionary: A - Zythum premiered at the Hammer Museum. Mark Robson performed her work for speaking pianist, Los Murmullos, on the LA series PianoSpheres, and more recently at the American Center in Paris. The acclaimed French harpist Helene Breschand performed her work Harpestra: Concerto for Two Harps, One Player.

Current projects include Resonare-a work commissioned by Aaron Khan for trumpet and spatialized audio; a new installment for The Well-Read Clavier for pianist Lorezo Marasso based on writings by Beppe Fenoglio and commissioned by the Ferrero Foundation; and an opera, This Lingering Life, blending and updating five ancient Noh dramas to convey their universal relevance. In the fall of 2017, she will be the featured international artist and keynote speaker at the Totally Huge New Music Festival in Perth, Australia.

Recordings of her music are available on Mode, New World Records, Ear-Rational, Innova, Music and Art, and Albany. As a member of the School of Music faculty at CalArts, she has developed highly original courses blending theater, art history, cultural topics, and music while encouraging students to actively create work incorporating what they are absorbing. These include HyperOpera; Concert Theater; Musical Reflections of Surrealism; Music of Harry Partch; Contemplative Practices, Musical Arts, Compassionate Mind; and Writing for Everything Else.

LeBaron serves on the boards of the American Composers Forum, where she is Vice-Chair, and as a Member of the Corporation of Yaddo. Also an accomplished harpist, she is renowned for pioneering methods of extended harp techniques, electronic enhancements, and notation in compositional and improvisational contexts. In the current season, she lectured on her music at the University of California Irvine, the University of Southern California, the University of California Los Angeles, and Cal State Fullerton. For the past two years, she led a master class for composition students visiting LA from Shanghai, under the auspices of the Bright Institute."

"Keith Tippett (born Keith Graham Tippetts; 25 August 1947) is a British jazz pianist and composer.

Tippett was born in Southmead, Bristol. The son of an English father who was a policeman and an Irish mother name of Kitty. Keith wrote music dedicated to her after she died. Keith was the oldest of three siblings and had Clive and Thomas as brothers. Tippett went to Greenway Secondary Modern school in Southmead, Bristol. He formed his first band when he was fourteen with school friends, such as Richard Murch, Mike Milton, Terry Pratt and Bob Chard. They were called the KT Trad Lads performing Traditional jazz. Later Keith formed a modern jazz trio in Bristol and played regularly at the Dugout Club in Park Row, Bristol. He studied Piano and Church Organ, was a chorister and played with the school and Bristol youth brass bands. He moved to London in 1967, to pursue a musical life.

In the late 1960s, Tippett led a sextet featuring Elton Dean on saxophone, Mark Charig on trumpet and Nick Evans on trombone. Tippett married singer Julie Driscoll and wrote scores for TV.

In the early 1970s, his big band Centipede brought together much of a generation of young British jazz and rock musicians. As well as performing some concerts (limited economically by the size of the band), they recorded one double-album, Septober Energy.

He formed, with Harry Miller and Louis Moholo a formidable rhythm section at the centre of some the most exciting combinations in the country, including the Elton Dean quartet, and Elton Dean's Ninesense. Around the same time, he was also in the vicinity of King Crimson, contributing piano to several of their records including "Cat Food" (and even appearing with them on Top of the Pops). His own groups, such as Ovary Lodge tended towards a more contemplative form of European free improvisation. He continues to perform with the improvising ensemble Mujician and more recently (2006) Work in Progress.

Tippett has appeared and recorded in a wide variety of settings, including a duet with Stan Tracey, duets with his wife Julie Tippetts, solo performances, and appeared on three King Crimson albums."

"Philipp Wachsmann. Born Uganda, 1944; violin, viola and electronics.

In the CD booklet to Gushwachs, John Corbett notes that Phillip Wachsmann came to free improvisation from a predominantly classical background, particularly via the contemporary experiments of "indeterminacy, graphic and prose-based scores, conceptualism and electroacoustics, listening to Webern, Partch, Ives, Berio and Varèse, reading 'Die Reihe' and interrogating the rhythmic, harmonic and melodic preoccupations of Western art music. Starting in 1969, Wachsmann was a member of Yggdrasil, an ensemble performing works by Cage, Cardew, Feldman, Ashley and others and in this group he used contact mikes on the violin and made his own electronic instruments, ring modulators and routing devices. Ironically, his studies with Nadia Boulanger in Paris (1969-1970) pushed him hard in the direction of free music. He recalls: 'Despite her neoclassical orientation, her insistence that composition is about the imagination of performance and its realisation, the live moment, and her stunning ability to make this happen was a powerful influence on me, steering towards 'performance' and therefore 'improvisation'.'"

Wachsmann moved from Yggdrasil to Chamberpot - recorded on Bead 2 - and shortly thereafter appeared on Tony Oxley's influential February papers, forward looking in the virtual 'industrial' orientation of some of the tracks, years before this became an accepted genre; the two musicians have continued to work together, in various groupings but notably in the percussionist's Celebration Orchestra. Philipp Wachsmann has also performed and/or recorded with: Derek Bailey's Company, e.g. on the recording Epiphanies; Georg Graewe; Barry Guy; Iskra 1903; King Übü Orchestrü; London Jazz Composers' Orchestra; Evan Parker, particularly as part of the Evan Parker Electronic Project; Quintet Moderne; Fred Van Hove's ML DD 4; Rüdiger Carl's COWWS (now CPWWS) Quintet; and Lines, with Martin Blume, Jim Denley, Axel Dörner and Marcio Mattos. He also plays as a solo musician.

Phillip Wachsmann also administers Bead Records."
