"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."

"Taku Unami was born in Tokyo, Japan, in 1976. He is a composer and improviser working with assorted stringed instruments, including the guitar, mandolin, and contraguitar, laptop and vibrating objects (from which he amplifies the inaudible vibrations). Despite being linked to minimal improvisation his music is hardly classifiable, being able to surprise listeners on every new release, raising unforeseen questions and forging new paths for improvisation. He is part of the group HOSE and has active collaborations with Mattin, Taku Sugimoto and Masahiko Okura. In the past he has worked with Radu Malfatti, Jean-Luc Guionnet, Klaus Filip, Masafumi Ezaki, Burkhard Stangl, Rhodri Davies and Keith Rowe, among others. Unami has also composed for film, including 'Lost My Way' (directed by Takeshi Furusawa) and 'In 1,000,000 years' (directed by Isao Okishima). He has released more than 30 records, both solo and in numerous groups and collaborations. He runs the influential label Hibari Music and co-organizes the Tokyo concert series Chamber Music Concerts with Taku Sugimoto and Masahiko Okura."
