"Barre Phillips (born October 27, 1934 in San Francisco, California) is a jazz bassist. A professional musician since 1960, he migrated to New York City in 1962, then to Europe in 1967.[1] Since 1972 he has been based in southern France where in 2014 founded the European Improvisation Center

He studied briefly in 1959 with S. Charles Siani, Assistant Principal Bassist with the San Francisco Symphony During the 1960s he recorded with (among others) Eric Dolphy, Jimmy Giuffre, Archie Shepp, Peter Nero, Attila Zoller, Lee Konitz and Marion Brown.[1]

Phillips' 1968 recording of solo bass improvisations, issued as Journal Violone in the USA, Unaccompanied Barre in England, and Basse Barre in France, is generally credited as the first solo bass record. A 1971 record with Dave Holland, Music from Two Basses, was probably the first record of improvised double bass duets.[2]

In the 1970s he was a member of the well-regarded and influential group The Trio with saxophonist John Surman and drummer Stu Martin.[1] In the 1980s and 1990s he played regularly with the London Jazz Composers Orchestra led by fellow bassist Barry Guy. He worked on soundtracks of the motion pictures Merry-Go-Round (1981), Naked Lunch (1991, together with Ornette Coleman) and Alles was baumelt, bringt Glück! (2013).[3]

He has also worked with (among many others) bassists Peter Kowald and Joëlle Léandre, guitarist Derek Bailey, clarinetists Theo Jörgensmann and Aurélien Besnard, saxophonists Peter Brötzmann, Evan Parker and Joe Maneri, and pianist Paul Bley.

Barre is the father of rock guitarist Jay Crawford from the band Bomb, of the bassist Dave Phillips and of singer Claudia Phillips, who was a one-hit wonder in France in 1987 with "Quel souci La Boétie". "

"Motoharu Yoshizawa (吉沢元治) (1931 - September 12, 1998) was an influential Japanese bassist known for playing in a distinctive free jazz and free improvisation style, sometimes deploying electronics and using the unusual self-designed five-string bass he referred to as the "Tiritack".

Yoshizawa collaborated with innumerable musicians over his long career; some of the better known include Masayuki Takayanagi, Masahiko Togashi, Takehisa Kosugi, Mototeru Takagi, Kaoru Abe, Steve Lacy, Dave Burrell, Derek Bailey, Evan Parker, Barre Phillips, Butch Morris, Elliott Sharp, Ikue Mori, Keiji Haino, Kan Mikami, Kazuki Tomokawa, Christopher Yohmei Blasdel & Tenko.

Yoshizawa began playing in a free style in the mid-1960s, in groups with Yosuke Yamashita and Kazunori Takeda, as well as in a famous jam session with Elvin Jones during John Coltrane's Japan tour of 1966. Yoshizawa's own trio with Mototeru Takagi was said to have been pivotal for Japanese free jazz, though no recordings survive. In 1969, Yoshizawa played with Masahiko Togashi's famous quartet and Masayuki Takayanagi's New Directions group, participating in both groups' landmark recording sessions of that year.Yoshizawa was a pioneer of solo bass performance, his experiments synchronous with those of Barre Phillips. He first played this style in 1969, though nothing was recorded until several years later. In the mid-1970s, Yoshizawa recorded three albums for solo bass. Later in the decade he had a fruitful collaboration with alto saxophonist Kaoru Abe, which led to the recording of one album, Nord.

In the 1990s, Yoshizawa began experimenting with an effects-laden, five-string bass of his own design. He spent six months living and playing in New York in 1989-90.
