Label says D Wing Demo
Label lists A1 as Frustration 1 and B3 as Frustration 2

Tracks A3 and B2 are not credited to Killing Joke on the record. A3 is incorrectly listed as Celtic Origin on sleeve and label, B2 as Belfast. Both tracks are from Killing Joke's BBC John Peel Session (recorded 5/3/1980) and were officially released in 2008 on the album The Peel Sessions 1979-1981.

A1 and B3 are two different instrumental mixes of the band's second single Frustration. B3 was officially released in 1986 on Family Album.

A2 was used as the backing track for The Slow Removal Of Vincent Van Gogh's Left Ear by The Bollock Brothers in 1982. A2 was officially released in 1987 on the compilation album Punk - A World History Vol.1 (reissued in the '90s on CD), credited to Lydon O'Donnell.
