All Lights Fucked on the Hairy Amp Drooling is a cassette released in 1994 by Canadian musician Efrim Menuck, using the name God Speed You Black Emperor!.[2][3][4][5] Given a limited release of 33 cassette copies in December 1994,[2] the album quickly fell into obscurity and was thought lost by the band's fans, often described as the "Holy Grail of Post-Rock".[6] Segments of the tape were leaked online in 2013 and the full recording surfaced in 2022, after which Menuck officially re-released the album on Bandcamp.[7]
