The duo, Pappenheim, Oscar Grönberg - piano and Tor Haugerud - drums, started playing in 2013. The duo plays free-improvised music with references to contemporary music and jazz, inspired by Paul Bley, Cecil Taylor, Paul Lovens and others. Pappenheim emphasizes the independent interactivity in their interactions where two equal voices meet. The music is always seeking the newly discovered, which can be both energetic and more silent or repetetive passages. Oscar Grönberg and Tor Haugerud are both experienced musicians in different contexts and has previously worked together in Trondheim Jazz Orchestra. Pappenheim recorded their first album ”Bekkenjordet”, which was released at the Trondheim based label Particular Recordings Collective. The duo has toured in Norway and Sweden.
