"Born Lucerne, 1952; saxophones, composer.

Urs Leimgruber has been active for many years in the areas of contemporary improvisation, composition, jazz and new music. One of his earliest associations was as a member of the electric jazz/free music group 'Om' with Christy Doran, Fredy Studer and Bobby Burri, and he later formed the 'Reflexionen' quartet with Don Friedman and Bobby Burri in New York. More recently, his own projects have included 'Ensemble Bleu', 'Xylem', e_a.sonata 02 with the ARTE saxophone quartet, as well as a long association with Fritz Hauser: as a duo with the ongoing Music for saxophone and percussion; in the Leimgruber/Roidinger/Hauser trio; a trio with Joëlle Léandre; and a trio with Marilyn Crispell. He later formed the 'quartet noir' with Marilyn Crispell, Joëlle Léandre and Fritz Hauser, a trio with Jacques Demierre and Barre Phillips and the group SIX with Jacques Demierre, Isabelle Duthoit, Charlotte Hug, Dorothea Schürch and Thomas Lehn. Urs Leimgruber has also performed extensively as a solo artist and has been involved in mixed media presentations, providing music for dance, radio plays and film.

Urs Leimgruber has undertaken concert tours in Western and Eastern Europe, USA, Canada, South America and Japan, and appeared at concerts and on recordings with such musicians as Steve Lacy, Fred Frith, Evan Parker, Joe McPhee, Lauren Newton, Michel Doneda, Keith Rowe, Günter Christmann, Sunny Murray and Günter Müller among many others."

"The pianist and composer Jacques Demierre was born in 1954 in Geneva. His musical itinerary is varied: improvisation, jazz contemporary music. As a composer, he is mainly self-taught. He writes for concert use, for the stage and for modern dance. He has received commissions for both jazz and contemporary music. The recording by singer Magali Schwartz of three pieces inspired by her voice is testimony to a rare artistic experience. Je deviendrai Médée, Désir d'azur: musique de danse and Bleu are the results of an intense collaboration which began in 1985-86 and, via vocal and instrumental improvisation, gradually led to a kind of common vocal territory, a veritable research laboratory which produced compositions as well as new ideas for vocal experimentation."

"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". "
