This was long before modern recording. We sang this live onto a quarter inch stereo tape. No overtracking, no signal processing, not even recording instruments and vocals on separate tracks.

Stone knives and bear skins, as Spock would say.

The master recently resurfaced and Bill applied some modern tools to clean up the recordings. This release includes No Morning, Ohio Blues, Outer Space Rocket Trilogy and more of Clif's songs along with Bill singing Space is Dark, Wind From Rainbow's End, One Last Battle and other classics.
