Kreuzberg is THE area for rock and indie in Berlin. The Magnet Club is located there, as is SO36, and the Lido. In the old days it was a cinema, in between it was a rehearsal stage for theatre companies. Thank god it is a place for concerts and club nights again since 2006.
Indie organisations such as Karrera Klub have occasional club nights here. The Lideo also has a nice beer garden annex winter garden annex smokers room.
