Before I joined Kraftwerk in 1971, I played guitar in a band called Spirits of Sound, whose members included (at times) amongst others singer Wolfgang Riechmann (Sky Records released his only solo album Wunderbar shortly after his death in 1978) and drummer Wolfgang Flür (later on Kraftwerk, now solo). The music of S.o.S. in the mid 60's first was the English pop and rock music of the times (Beatles, Kinks, Rolling Stones ).

Back then and later on when I was in NEU! and Harmonia I was too much preoccupied with my own music to be aware of the German music scene, let alone following it actively. But changes which were happening with S.o.S. (namely the development of individual ideas and the effort to distinguish from the Anglo- American rock patterns) also helped me recognize other musicians within my immediate vicinity.

As a conscientious objector I did my community service in 1971 in a psychiatric hospital and a friend there, who also was a guitar player, invited me one day to join him recording film music with a band named Kraftwerk which I didn't know at the time. I came along and jammed at this session together with Ralf Hütter and a drummer (I believe his name was Charly Weiß). Florian Schneider and Klaus Dinger were present as listeners and everybody liked the spontaneous music we did together.

NEU!'s music will always ("für immer") be a part of me and I absolutely stand to what we've created. Of course I have changed since and I judge my contributions to NEU!'s music of the 70's in a historical context. They were both a description of my feelings back then as well as an expression of my musical abilities and limitations. It would be a mistake to ignore the time factor and it would be an artistic shortcoming to pick up on the old concept without doing any changes. There is no way this is going to happen anyway.
