Rainer Bürck and Hartmut Dorschner first played together at the "Festival Frei Improvisierter Musik" in Dresden on September 25, 1998. They had never played together before this. The only "preparation" for this concert was a short rehearsal of maybe half an hour in the afternoon before the show. The concert went very well, and so they decided to continue their collaboration. They also performed at the FIMU Festival in Belfort/France in May 1998 and are currently planning further activities.
