The Werkstatt der Kulturen (Workshop of Cultures) is a place where all sorts of different traditional and contemporary cultural practices and ares are presented. As such, expect a diverse mix of styles, origins and influences. But you can expect not only world music and black music, but also electronic, oriental and african mmusic. Not only jazz, but a diverse mix of global sounds, that will never leave you bored.
We don't know about any jam sessions at Werkstatt der Kulturen.
