Drumlegend Jim Chapin counts Claus amongst the league of international top drummers: Besides he wide stylistic range of his playing especially "Open Handed Playing" and the so called "Moeller Technique" have become his trademark - for the latter there is quite a number of people who see Claus already as the legitimate successor of his technical mentor Chapin. In addition to his educational writing for the drums & percussion magazine he teaches at the University for Music and Performing Arts in Frankfurt, the Berufsfachschule für Musik in Dinkelsbuehl and maintains a busy schedule of clinics and private teaching.
One of the highlights at the Frankfurt Show 2006 was the SABIAN LIVE performance together with John Blackwell, Zoro and Dom Famularo. His workshops are known for a special mixture of education and Claus teaching skills along with presenting his unique solistic and musical qualities as well. As a clinician for SABIAN cymbals, VIC FIRTH sticks. MAPEX drums and REMO drumheads he took part in many leading meetings and drum events.
Studiowork and numerous tours and concerts throughout Europe with a variety of bands and musicians have earned him credits in different genres of music ranging from Jazz, Latin, Bigband, Top 40 to TV-Jingles ... you name it.
