"Radu Malfatti is an Austrian trombone player and composer. He was born in Innsbruck, in the province of Tyrol, on December 16, 1943. He has been described as "among the leaders in redefining the avant-garde as truly on-the-edge art." His work "since the early nineties... has been investigating the edges of ultraminimalism in both his composed and improvised work." He also operates B-Boim, a CD-R only record label focusing on improvised and composed music, much of it his own."

"Philipp Wachsmann. Born Uganda, 1944; violin, viola and electronics.

In the CD booklet to Gushwachs, John Corbett notes that Phillip Wachsmann came to free improvisation from a predominantly classical background, particularly via the contemporary experiments of "indeterminacy, graphic and prose-based scores, conceptualism and electroacoustics, listening to Webern, Partch, Ives, Berio and Varèse, reading 'Die Reihe' and interrogating the rhythmic, harmonic and melodic preoccupations of Western art music. Starting in 1969, Wachsmann was a member of Yggdrasil, an ensemble performing works by Cage, Cardew, Feldman, Ashley and others and in this group he used contact mikes on the violin and made his own electronic instruments, ring modulators and routing devices. Ironically, his studies with Nadia Boulanger in Paris (1969-1970) pushed him hard in the direction of free music. He recalls: 'Despite her neoclassical orientation, her insistence that composition is about the imagination of performance and its realisation, the live moment, and her stunning ability to make this happen was a powerful influence on me, steering towards 'performance' and therefore 'improvisation'.'"

Wachsmann moved from Yggdrasil to Chamberpot - recorded on Bead 2 - and shortly thereafter appeared on Tony Oxley's influential February papers, forward looking in the virtual 'industrial' orientation of some of the tracks, years before this became an accepted genre; the two musicians have continued to work together, in various groupings but notably in the percussionist's Celebration Orchestra. Philipp Wachsmann has also performed and/or recorded with: Derek Bailey's Company, e.g. on the recording Epiphanies; Georg Graewe; Barry Guy; Iskra 1903; King Übü Orchestrü; London Jazz Composers' Orchestra; Evan Parker, particularly as part of the Evan Parker Electronic Project; Quintet Moderne; Fred Van Hove's ML DD 4; Rüdiger Carl's COWWS (now CPWWS) Quintet; and Lines, with Martin Blume, Jim Denley, Axel Dörner and Marcio Mattos. He also plays as a solo musician.

Phillip Wachsmann also administers Bead Records."
