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

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.

The problem was the journalists who also did not understand much of my music, but they wrote about it. I think you fell into the usual trap laid out by parts of the press and other writers: that the poor musician has always to fight the evil companies and managers.

I did not start IC and Inteam to have control over my music. I had control before and after.

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.

Sometimes I like to make music together with a singer or with singers.

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.
