As always in a musical collaboration: One has to like each other. As simple as that.

Yes, I was invited to make the sound environment at a booth of a huge electronic company, during the Hanover Industrial Fair in 1973. It was a job. Slightly good paid. But not as much as my producer then told the press.

And of course, the musician - if he's serious - always answers: My last album is my best, otherwise I wouldn't have done it.

I never had many problems to do my music and to give it to a record company. Rarely do they try to argue with me about my music, probably because it's still too far-out.

When I came back I had to realize that IC was not in a very good shape - all the much money that we had because of the huge Ideal success, was gone. I was very upset.

How did this or that change my music? The only time I have to think about it is when an interviewer asks me that.

A concert is a concert is a concert is a concert. An album is an album is an album is an album. Musically, both have nothing in common.
