To mark its 40th anniversary in 2007 the Kunsthalle Düsseldorf organized the Düsseldorf Sounds Festival of Art and Music from Düsseldorf. One particularly noteworthy event was staged in the Kunsthalle's cinema auditorium: the only Dieter Moebius and Stefan Schneider collaboration ever. Dieter Moebius (1944-2015) was a member of the group Cluster with Hans-Joachim Roedelius. Stefan Schneider is the co-founder of the seminal neo-krautronic bands Kreidler and To Rococo Rot. The two musicians met briefly in Berlin to discuss the performance. On the night of the concert, they improvised everything.
