Stefan has played with different Celtic folk & traditional bands, but listens to most kinds of music and is the main musical contributor of the historical theatre troupe Kompani Bastard. His style of playing, largely based on the musical dialects of fiddlers from the border regions of Norway/Dalecarlia, is characterized by great freedom of improvisation and is also tinted by both Celtic and Balkan music.
