 These two songs also serve as a sort of test of the reproduction capabilities of an audio system, with the extremely low bass tones on the former song and the shrill opening riffs on the latter song overwhelming many sound systems.The album was reissued in May 2020 after a remaster from the original United Artists master tapes by Atomhenge, Hawkwind's dedicated Cherry Red Records sub label.This reissue includes the first release of the album on CD which along with the vinyl reissue features restored artwork.
