The album, originally released in 1973 under artist name "Upsetters 14 Dub",[2] was pressed in only 300 copies and issued only in Jamaica.

According to Pauline Morrison, this was the first ever dub album that came out, although there is a lot of speculation on the subject.

[3] Nevertheless, this was the first stereo dub album, as well as the first to include reverb.

[4] Later pressings released as Blackboard Jungle Dub have a different track listing.

The album was re-issued as a 3x 10" colored vinyl box set as part of Record Store Day in April, 2012.
