Edgar met Klaus briefly for the first time in July 1969 outside the Zodiak Club in Berlin. He was a drummer for a band called Psy Free. Because Edgar was looking for a new drummer for TD they met again a week later for an audition in a small club. A few weeks later Klaus played drums on a rehearsal tape which became TD’s first LP Electronic Meditation. A couple of month later Klaus left the band because he got married. That was it!
