Klaus was a well known master of the tibetan singing bowls and published an absolutely unique discography in this genre.
He was also a member of the band " Popol Vuh " founded in 1970 - some insiders may be familiar with this group... His very deep and psychological kind of music is used worldwide for therapy purposes.
We highly recommend his work, especially his hypnotic Sufi-music inspired by his trips to the Middle East.
