A fifth song, Towers of Darkness (2:18) was recorded during these sessions but not included on the original release. The EP was supposed to include the track The Crucifix but Mark Briody did not own an acoustic guitar and could not find one to borrow (as he had, for the second 1981 demo), so the track was not recorded.The EP was originally self-titled. It has been referred to as The Tyrant's EP, Battle Zones, and Tyrants, with some variation of the first and the last being preferred by the band nowadays.
