Klaus studied drums at the Musikfachschule in Berlin-Friedrichshain. He started his professional career in 1975 and got his first SONOR kit in 1976. In 1979 he started playing with the "Puhdys", one of the most popular German bands, playing their concert number 3000 in 1999! The band had its 40th jubilee in 2009 and played a sold out show in the O2 arena in Berlin. The band has sold more than 24 million records throughout their history.
In 1981 he visited the SONOR factory, by invitation from Mr. Horst Link and bought a 9-piece Rosewood drumkit that he played until 1989.
