"Jack Wright was born Pittsburgh PA in 1942 and grew up around Philadelphia and Chicago. He began playing saxophone in 1952, with private instruction; also singing in groups large and small through 1964, including a blue grass trio (playing washtub bass), which recorded an album, "Undertaking Bluegrass." After this he ceased playing music. He attended Lafayette College in Easton PA, where he studied European history and literature and graduated 1964; Johns Hopkins University, MA in European history, 1972; taught history at CCNY in NY and then Temple U. 1967-72, after which he left the academic world. In this latter period he was involved in left politics, organizing mainly on a community level, and began to become involved with music again.

Described twenty years ago as an "undergrounder by design," Jack Wright is a veteran saxophone improviser based mainly in Philadelphia. He has played mostly on tour through the US and Europe since the early 80s in search of interesting partners and playing situations. Now at 72 he is still the "Johnny Appleseed of Free Improvisation," as guitarist Davey Williams called him in the 80s, on the road as much as ever. And he continues to inspire players outside music-school careerdom, playing sessions with visiting and resident players old and new. His partners over the years are mostly unknown to the music press, and too numerous to mention. He's said to have the widest vocabulary of any, including leaping pitches, punchy, precise timing, sharp and intrusive multiphonics, surprising gaps of silence, and obscene animalistic sounds. A reviewer for the Washington Post said, "In the rarefied, underground world of experimental free improvisation, saxophonist Jack Wright is king"."

"John Shiurba is a composer and guitarist whose musical pursuits include improvisation, art-rock, modern composition and noise. Shiurba has recorded and toured the U.S. and Europe as a member of the bands Eskimo, The Molecules and Spezza Rotto, as a member of the Merce Cunningham Dance Company, Anthony Braxton's ensemble and the SFSound Group, and as an improvisor.

Shiurba has conducted the premieres of his compositions at ODC in 2005 ("Moon Cycle" for SFSound) at New Langton Arts in 2002 ("Triplicate") and at SFAlt in 2002 ("5x5 1.4" for SFSound). Shiurba was invited to play at the Seattle Improvised Music Festival in 1998, at the High Zero Festival in Baltimore in 1999, at the SFAlt Festival in 2004 and at the Olympia Experimental Music Festival in 2002 and 2004, and at the Push International Performing Arts Festival in Vancouver in 2007.

As a guitarist Shiurba has developed a unique and personalized approach to the guitar. Through the use of extended techniques and unusual preparations, he expands the traditional sound range of the instrument, producing stunning, often unrecognizable results. Cadence Magazine calls Shiurba a 'wildly creative guitarist... anti-jazz, anti-everything else, yet utterly compelling.'"

"Bhob Rainey is an award-winning composer / performer, saxophonist, and sound designer. He holds a Masters in Music Composition from New England Conservatory ('97), where he studied with iconoclastic microtonalist Joe Maneri, jazz legends Paul Bley and Ran Blake, and the mathematically gifted composer Pozzi Escot.

In 1998, with trumpeter Greg Kelley, Rainey founded the duo Nmperign, which was highly influential in an emerging phase of non-idiomatic improvisation often referred to as "lowercase" or "EAI" (Electroacoustic Improvisation). In 2000 he founded The BSC, an improvising large ensemble, in which he developed techniques for an improvisational discipline that were eventually outlined in his 2011 publication, Manual. Throughout the late 1990's and early 2000's he performed globally and collaborated with numerous improvisers across generations, including Axel Dörner, Andrea Neumann, Günter Müller, Michel Doneda, Lê Quan Ninh, and many others.

By the mid-2000's, while continuing to work in the realm of improvisation, Rainey began to produce electronic and algorithmic works. He spent five years collaborating with German composer Ralf Wehowsky (RLW) on the 2007 release, I don't think I can see you tonight, which, along with Nmperign and Jason Lescalleet's Love Me Two Times (2006), established him as a formidable electronic composer who synthesizes streams of Musique Concréte, computer music, and improvisation.

Throughout his career, Rainey has sought out cross-discipline collaborations, working especially with theater makers and choreographers. Since 2012 he has worked with theater company New Paradise Labs, composing for The Adults, which premiered at the 2014 Philadelphia Fringe Festival, and O Monsters (2016). He created the soundtrack to Leah Ross's 2013 film, Levitate, which premiered that year at the Rooftop Film Festival in New York City, and he performed live in Jungwoong Kim's and Marion Ramirez's site-specific dance work, Capsized, at the National Asian American Theater Festival in Philadelphia in 2014.

Rainey was awarded the Pew Fellowship in the Arts in 2013, and in 2014 he received a Subito grant from the American Composers Forum to complete a multimedia project with filmmaker Catherine Pancake. He is currently working with New Paradise Laboratories on a musically-driven follow up to O Monsters, with Jungwoong Kim on a multimedia dance installation, and with Leif Elggren and CM Von Hausswolff on the inauguration of the "Kingdom of Elgaland-Vargaland Embassy" in Philadelphia.

To date, Rainey has over 30 releases as a leader or co-leader."

"Drummer Eric Rosenthal is based out of the Boston area. The former student of Ed Blackwell has studied and performed more than American jazz drumming; he has also delved into West African traditional and South Indian classical percussion. Rosenthal has performed and improvised with Anthony Braxton, Mat Maneri, Pandelis Karayorgis, Mario Pavone, and the Either/Orchestra. He has performed all over North America and Europe, and appeared in Greece at the Patras Jazz Festival, at Montreal's North Sea Jazz festival, even at Finland's Pori Festival. Besides producing his own improvised music recordings, he also appears on CDs with the Hypnotic Clambake and the Zairean soukous band Freestyle. The late '90s found Rosenthal busy in the group Naftule's Dream. The band has two releases on John Zorn's Tzadik label, Search for the Golden Dreydl and Smash, Clap!"
