The drummer, performer, artist and composer Sven-Åke Johansson is one of the legendary protagonists of free improvised music. As a drummer Johansson defined the European Free Jazz with EMT and the duo with Alexander von Schlippenbach. In the 1970s he began to record his ideas for performances in drawn scores. Searching for new sounds, since the early 1960s, Johansson has been working on the musicalization of everyday objects committed to the continuous expansion and poetization of the acoustic material. Within the framework of the 6th Berlin Biennale his large-scale drawings of helicopters are on view at Oranienplatz 17.
