One of the most prolific experimental musicians of the Austrian scene, Hautzinger has worked with many big names of the international avant-garde, has run many own ensembles (Regenorchester, Gomberg, Dachte Musik, Poet Congress). At first strongly influenced by Miles Davis' modal jazz, Hautzinger's trumpet playing gradually evolved toward more con-templative, impressionistic realms that bear similarities with Bill Dixon's sound world.
He has been much in demand as a collaborator with the likes of Lou Reed, John Cale, Keiji Haino, Hamid Drake, Jamaladeen Tacuma, Elliot Sharp, Otomo Yosihide, Butch Morris, Derek Bailey, Luc Ex, Xavier Charles, and Isabelle Duthoit.
Hautzinger has developed his quarter-tone trumpet to a whole new kind of expression, which he elicits bizarre sounds and noises. In his solo per-formance, he creates adventurous soundscapes that sound more like electronic music then a trumpet.
He taught composition, structure analysis, improvisation, from 1989-2008 at the University for music and arts in Vienna. Hautzinger current-ly composes for film and radio, dance projects and theatre, and tours and performs live worldwide.
