BGA stands for Brent Gutzeit Archive (2002-2006) (2018-present). This small-run label was founded by Brent Gutzeit to release his own works. All editions were on CDr, limited to 20-50 copies. There were two series in the catalog: BGA00* on standard CDr and BGA30* on 3" mini-CDr. The label reactivated in 2018, releasing even more limited CDr and cassette editions, usually in limited editions of 1-10. the Other labels operated by Gutzeit includes BOXmedia (1997-2004), Trust Lost (2006-2015).
