Olaf Rupp, born 1963, plays improvised music on the acoustic and electric guitar. The organic flow of his music is controlled neither by chance nor by wilful decisions. In his music he explores how more or less dense murmurations of notes (motion-clusters) can be perceived as one agglomerated sound in motion. Olaf Rupp has been touring in many countries and performed with musicians such as Paul Lovens, Tristan Honsinger, Peter Brötzmann, Butch Morris, and Michael Wertmüller. Important groups are among others the duo XENOFOX with Rudi Fischerlehner, DIE DICKEN FINGER with Oli Steidle and Jan Roder (also a quartet with Peter Brötzmann) and Weird Weapons with Tony Buck and Joe Williamson.
