Billy Bang (September 20, 1947 – April 11, 2011), born William Vincent Walker, was an American free jazz violinist and composer Barry Altschul (born January 6, 1943, New York City) is a free jazz and hard bop drummer who gained fame in the late 1960s with thepianists Paul Bley and Chick Corea. Altschul, having initially taught himself to play drums, studied with Charlie Persip during the 1960s. In the latter part of the decade, he performed with Paul Bley. In 1969 he joined with Chick Corea, Dave Holland and Anthony Braxton to form the group Circle. At the time, he made use of a high-pitched Gretsch kit with add-on drums and percussion instruments, which he integrated seamlessly in a whirlwind of sound. Joe Fonda (b. December 16, 1954) is an American jazz bassist. Fonda was born in Amsterdam, New York to parents who both played jazz. He played guitar as a youth but switched to bass guitar later on. He studied bass at Berklee College of Music, where he also began playing upright bass. He played in the New Haven, Connecticut area in the early 1980s, and recorded with Wadada Leo Smith. In 1994 he began playing with Anthony Braxton, collaborating with him extensively for the next five years. He and Michael Jefry Stevens co-lead an ensemble, the Fonda-Stevens group, that began in 1991 and has continued through 2009. The group has recorded 10 cds and continues to perform extensively in Europe and the United States. Since the late 1990s Fonda has recorded often as a bandleader. Fonda has also explored dance in relation to jazz music; he played bass with a dance company in the 1980s and incorporated a tap dancer into his ensemble for the albums From the Source andThe Healing.
