The first disc is a remastered version of the 1990 Virgin CD reissue of Correlations, recorded and mixed at Panne-Paulsen Studio, Frankfurt, in 1978 by Mick Glossop and originally released by Virgin in 1979. The second disc is the first release of Phantasus, Manuel Göttsching and Udo Arndt's original 1978 recording and mix of the album that was partially re-recorded and totally remixed to become Correlations (Phantasus was Göttsching's intended title, which he changed to Correlations after UK fans told him that the English can't pronounce "phantasus"). The third, fourth, and fifth discs are The Making Of, which includes a 12-page booklet. Performed by Manuel Göttsching (guitar, synthesizer, sequencer), Lutz Ulbrich (guitar, synthesizer, piano, mellotron), and Harald Großkopf (drums, percussion, synthesizer).
