If  you happen to speak (or at least understand) german and have a taste for intelligent Hip-Hop I strongly advise you to check out a show by Käptn Peng and his Tentakels.

Ive been there yesterday (being one of the few lucky ones that got in with paying at the door) and while I really appreciate their studio produced stuff its twice as ossom live!

If you have nothing better to do you should really check them out!
