Ben Schadow
On the bass of Bernd Begemann & die Befreiung, on Dirk Darmstädter's 'me and cassity', on 'pretty mery k', sometimes on the guitar on 'Erobique', in Hamburg's Thalia Theater on Don Quixote, or on tour with his good friend Pele Caster you might have seen Ben before without knowing it.
But with 100% certainty you have the one or the other album on your (virtual) shelf on which he plays guitar or bass or which he produced.
Time to get a more detailed picture.
