'70-'80 features album material only, with the exception of the 7" remix of the track Monolight, taken from Monolight (1977). This one was unavailable elsewhere until it was re-released as part of the compilation box The Virgin Years 1977-1983.
Additionally, one vinyl side features previously unreleased solo material by Edgar Froese, Chris Franke and Peter Baumann, respectively, which had not been re-released on any official album since, until these tracks finally appeared in the In Search Of Hades box (2019), almost fourty years after there initial release. Baryll Blue, the solo composition by Edgar Froese stems from 1978 and might be a leftover from his Ages solo album. Chris Franke's track Chimes And Chains, recorded in 1979, might have been intended for his first solo album that he was apparently working on during the late seventies, but which never saw the light of day. (His first album, Pacific Coast Highway (1991), apparently consists of different material, all recorded after his departure from the band in 1987.) Finally, the track Haunted Heights, composed by Peter Baumann, originally was planned to be a part of the collagesque studio composition Desert Dream from Encore (1977) but apparently had been refused by the other band members.
Most copies of the box 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
