"Julius Arthur Hemphill (January 24, 1938 - April 2, 1995) was a jazz composer and saxophone player. He performed mainly on alto saxophone, less often on soprano and tenor saxophones and flute.

Hemphill was born in Fort Worth, Texas, and attended I.M. Terrell High School (as did Ornette Coleman). He studied the clarinet with John Carter, another I.M. Terrell alumnus, before learning saxophone. Gerry Mulligan was an early influence. Hemphill joined the United States Army in 1964, and served for several years, and later performed with Ike Turner for a brief period. In 1968, Hemphill moved to St. Louis, Missouri, and co-founded the Black Artists' Group (BAG), a multidisciplinary arts collective that brought him into contact with artists such as saxophonists Oliver Lake and Hamiet Bluiett, trumpeters Baikida Carroll and Floyd LeFlore, and writer/director Malinke Robert Elliott.

Hemphill moved to New York City in the mid-1970s, and was active in the then-thriving free jazz community. He gave saxophone lessons to a number of musicians, including David Sanborn and Tim Berne. Hemphill was probably best known as the founder of the World Saxophone Quartet, a group he formed in 1976, after collaborating with Anthony Braxton in several saxophone-only ensembles. Hemphill left the World Saxophone Quartet in the early 1990s, and formed a saxophone quintet.

Hemphill recorded over twenty albums as a leader, about ten records with the World Saxophone Quartet and recorded or performed with Björk, Bill Frisell, Anthony Braxton and others. Late in his life, ill-health (including diabetes and heart surgery) forced Hemphill to stop playing saxophone, but he continued writing music until his death in New York City. His saxophone sextet, led by Marty Ehrlich, also released several albums of Hemphill's music, but without Hemphill playing. The most recent is entitled The Hard Blues, recorded live in Lisbon after Hemphill's death.

A source of information on Hemphill's life and music is a multi-hour oral history interview that he conducted for the Smithsonian Institution in March and April 1994, and which is held at the Archives Center of the National Museum of American History in Washington, D.C."

"Born 1944 in Germany, died 21 September 2002 New York City; double bass, voice, tuba.

Peter Brötzmann (Corbett, 1994) recounted that 'there was this young guy trying to play the bass, who was Mr Kowald, at that time seventeen years old. Peter lived with his parents. I had my little studio, so he was always hanging out at my place. But he had to be at home at 10.00, he was drinking milk. But we changed that, very soon. His parents were always very angry with me, because he never showed up at home anymore, he dropped studies of ancient languages, Greek and all that.' By this time (1962) Peter Kowald had been playing bass for two years and, with different drummers the two Peters were playing Mingus, Ornette, and Miles Davis things as well as listening to Coltrane, Stockhausen, Cage et al. Kowald was part of the European tour undertaken by the Carla Bley/Michael Mantler band in 1966 (also featuring Brötzmann) and then came work with other German musicians, membership of the Globe Unity Orchestra and the first recordings: Globe Unity, For Adolphe Sax and Summer 1967, recorded during a brief vacation in London. In particular, Evan Parker credits this visit to London for his invitation to play in the Pierre Favre/Irene Schweizer quartet and his subsequent longstanding involvement with German (and other European) musicians. Kowald's work with Brötzmann continued - on and off - on record at least, to the time of Kowald's death and included the Cooperative Trio with Andrew Cyrille, a duo on the Duos project and a recent mix of free jazz, hip-hop and rap.

Peter Kowald was a member of Globe Unity Orchestra for 12 years (1966 to 1978) and for much of this time played less of a side-man role and more of an equal partner - for example, conducting the band - with the person to whom the group has become most associated, Alex von Schlippenbach. His influence is particularly noticeable on Jahrmarkt/Local fair where the two sides of composition are by Kowald (as is the second side of Live in Wuppertal and he is also credited, along with Paul Lovens as 'producing' the record, presumably sorting out the sprawling theatricality and poor sound into two 'meaningful' fragments. In his notes to 20th anniversary, Schlippenbach emphasises the importance of Kowald in creating a programme that became a lot more 'colourful'; while further pointing out that he and Kowald gradually drifted further apart 'until one fine evening after lengthy discussions which resulted in a fight in a pub in Wuppertal, this chapter also closed'. However, before this ending, from 1973 to 1978, Kowald also worked with the Schlippenbach trio (Schlippenbach/ Parker/Paul Lovens), turning it for much of this time into a regular quartet.

Throughout his career, Peter Kowald worked with a wide variety of improvising musicians worldwide and in many considered and unusual situations. He recorded bass duets with Barry Guy, Barre Phillips, Peter Jacquemyn, Maarten Altena, Damon Smith and William Parker, released two solo bass recordings, and had regular groups with Leo Smith and Günter Sommer; with Joëlle Léandre and dancer Anne Martin (Trio Tartini); with dancers Cheryl Banks and Arnette de Mille and cellist Muneer Abdul Fataah (Music and Movement Improvisation); a trio with pianist Curtis Clark; a trio with Canadian alto saxophonist Yves Charuest and Louis Moholo; and Principle Life with Jeanne Lee, Klaus Hovman, and Marilyn Mazur. During the period 1980 to 1985 he was a member of the London Jazz Composers' Orchestra. He has spent periods in the US and in Japan and recorded three duo LPs (two CDs) with US, European and Japanese musicians. He also lived in Greece and similarly played and recorded with the Greek musicians Floros Floridis and Ilias Papadopoulos. By contrast, the 12 months May 1994 to May 1995 was designated Kowald's 'Year at home' project which comprised a mixture of solo works - out of which, to some extent, the last solo CD grew (Was da ist) - and group performances.

In addition, Peter Kowald collaborated extensively with poets and artists and with the dancers Gerlinde Lambeck, Anne Martin, Tadashi Endo, Patsy Parker, Maria Mitchell, Sally Silvers, Cherly Banks, Arnette de Mille, Sayonara Pereira, and Kazuo Ohno. Specific works included Die klage der kaiserin (1989) with Pina Bausch, Short pieces (since 1989) with Jean Sasportes, The spirit of adventure (1990) with Anastasia Lyra, Wasser in der hand (1990/91) with Christine Brunel, and Futan no sentaku/The burden of choice (1990/91) with Min Tanaka and Butch Morris."
