Music and More

For some reason, I do like playing guitar every once in a while, and occasionally record things:

Impro on II-V-I - this video recording is part of a performance by the lyrics group (Sprecherkreis) at University of Potsdam in 2008.

Nardis - this demo recording was done in 2006 with Ramona Geissler on bass and Dana Leichsenring on vibraphone. In this line of recordings, we managed to do several tracks, such as Freddie Freeloader, Have you met Miss Jones, and Black Orpheus.
