“The B12 Records Archive” is a 7 volume double CD series collecting the entire B12 Records music archive from 1990-2005 including 96 tracks and 27 previously unreleased tracks.

There are four great B12 compilations out already. I recommend to check them out in: The Aciddome MP3 Collection.

UPDATE: B12 Archive Volume 4 is now also available.
