Axel Dörner, born in 1964, studied trumpet and piano in Cologne and Arnheim, The Netherlands. When he moved to Berlin in 1994, he started collaborating in different formations with Sven-Åke Johansson, which continues until present time. Since 2000 he is working on an electronic extension of his music on the trumpet (together with Sukandar Kartadinata). Axel Dörner is one of the most unique voices in free improvisation. He developed a completely individual language for the trumpet in the late 1990s. Most of the ensembles he is part of are characterized by a non-hierarchical collaboration of the musicians involved.
