Axel Kühn's main job is bassist of Kühntett. But he has a hobby: to play even more bass. He accompanied Anne-Sophie von Otter and Peter Mattei in the Mahler Chamber Orchestra, is a member of the Chris Gall Trio, played in the Anne Czichowsky Quintett and the Boston Collective. Pianist Christoph Heckeler studied under John Taylor, Tom van der Geld, Don Friedman and Adam Makowicz, among others, and got his first performance experience playing alongside Dave Liebman, Peter Herbolzheimer, Ack van Rooyen, Adrian Mears, Gunther Schuller and others. Marcel Gustke has not only been drumming in Kühntett since 2005, but also for Barbara Dennerlein since 2006. And because he feels at home in all styles between pop, jazz, soul and funk, you could already see and hear him with Cassandra Steen, Nils Landgren, Andi Maile and Wolfgang Puschnig. Saxophonist Alexander "Sandi" Kuhn studied under Frank Tiberi and Joe Lovano, among others, at the Berklee College of Music in Boston and under Prof. Bernd Konrad at the State College for Music and the Performing Arts in Stuttgart. In addition to Kühntett, he dedicates himself to his own band KuhnStoff and the Boston Collective.
