Four discs have been reissued this round, all of which were originally out on Rough Trade, subsequently released by Play It Again, Sam, WaxTrax! and/or Nettwerk. These four releases are scatterings across the growth curve—represented by 1981's 'Heartbeat', 1988's 'Songs of Love and Lust', and two releases from 1990: 'Trance' and 'Techno Primitiv.'
