Cologne, taught by
Karlheinz Stockhausen,
Luciano Berio,
Henri Pousseur, and
Earle Brown. In the late 1960s, Plank began producing albums and working as a sound engineer, and became involved in the underground music scene, which was spreading from
Berlin throughout Germany. In 1969 he served as engineer for the first
Kluster album,
Klopfzeichen, which was released the following year. His long association with
Dieter Moebius and
Hans-Joachim Roedelius of Kluster and later
Cluster endured until his death. He also served as engineer for
Alexander von Schlippenbach's album
The Living Music, which was released in 1969, the first of a long list of engineering and production credits. and went on to produce and/or engineered many recordings by significant German progressive/experimental music acts often referred to as
krautrock internationally, including
Kraftwerk,
Organisation,
Neu!,
Cluster,
Harmonia,
Night Sun,
Holger Czukay and
Guru Guru. Plank's other production credits include
Liaisons Dangereuses,
Phew,
Einstürzende Neubauten,
Ástor Piazzolla, Psychotic Tanks,
DAF (including the classic single "Der Mussolini"),
Les Rita Mitsouko, and
Nina Hagen. According to
René Tinner and Stephan Plank in a radio documentary about the life of Conny Plank, it was
Brian Eno's idea that Plank should produce the
U2 album
The Joshua Tree instead of him. After being introduced to the band by Eno and after a short meeting, Plank turned down the job ("I cannot work with this singer"). According to the companion website of the documentary film
Conny Plank – The Potential of Noise (but not the film itself), after the meeting, Plank firstly asked for time for a second thought. In the meantime he attended a U2 concert at
Freilichtbühne Loreley, where U2's Bono introduced Plank to the audience as their new producer, after which Plank is said to have left the concert and never communicated further with any member of U2. ==Death==
