One vinyl side features previously unreleased solo material by Edgar Froese, Chris Franke and Peter Baumann, respectively, which has not been re-released on any other album since. And there is a remix of the track Monolight, unavailable elsewhere until it was re-released as part of the compilation box The Virgin Years 1977-1983.
Furthermore most boxes contained a LP sized 28-page booklet with a discography, a biography and many photographs of the band.
This box has never been released in CD format.
4LP: 301 407; identical to UK version with the German order number on a sticker fixed on the box back side
