I know it's a long way to Berlin, Germany for most of you but I've just received the newsletter from indie label Denovali and they announced a 7.1 Surround Concert by Bersarin Quartett as part of their label night. Thought I'd post this here, in case anyone's interested. Denovali release mostly dark instrumental/experimental/avantgarde/drone stuff and I can attest their label nights are usually great if you're at least slightly into this kind of thing.
