This tape is a bit of a mystery. I managed the band when they got back together in 1987, and I do not remember this demo at all. In addition, the track listing on the cover does not match the tape. It does start out with Frontline (as listed), but the second song is Death in Disneyland which is not even shown in the track listing. This version of DiD is one I don’t recall hearing before- it sounds like a studio demo, but not from either of the 2 studio demos made in 1987/88. All other versions of the songs, except Death in Disneyland, appear to be from the “Power Corrupts” demo session.

EDIT: Mike let me know that this is not the Evil’s End demo, which was only CD tracks anyway. This has the Metal Massacre IX track plus Power Corrupts demo tracks.
