"Thomas Rehnert lives and works in Berlin. Influenced by the European free jazz of the 1970s, he played drums in various punk bands in Berlin (West) in the 1980s. In the punk and experimental music environment of those years, he began to deal with improvised and electroacoustic music, machine music and automata. Today he builds his own drum kits and develops playing techniques and collective improvisation concepts. He expands the acoustic drum sounds partly with live electronics. For several years he has been building autopoietic installations from analogue modular systems that generate sounds, videos, drawings and sculptures. As a drummer, he plays in various formations and is involved in various interdisciplinary projects (theatre, radio, visual arts). He works as a composer, sound artist, drummer and sound designer."
