Christian Jaksjø’s musical background includes studies of improvisation, composition, and electro-acoustic music, an extensive performing career on trombone, euphonium, and related instruments, interdiciplinary experimental studies of dynamic form with architects, designers and engineers, along with a concurrent, groundbreaking creative practice as a composer. Pivotal to his work, both as a composer and as an improviser, is rendering audible the inaudible: underlying forces as well as otherwise imperceptible patterns. Christian Jaksjø lives and works in Oslo (where he was born in 1973) and in Frankfurt am Main (where he, since 2003, plays trombone in the hr-Bigband).
