Das Projekt Burn Station macht am Dienstag Station in Berlin. Aus dem Eigenlob:

BURN STATION is a mobile copying station which … supports the free distribution music and audio … BURN STATION is a social event which congregates people together to listen, select and copy net label and net radio audio files with a Copyleft Licence. BURN STATION is an open source and a non-commercial project involving the new means of free networked distribution.

Am Dienstag in der Maria ist unter anderem wohl das Kraftfuttermischwerk dabei, was ich sehr empfehlen kann.
