This 2 disc edition of the band's debut features the original mono version plus the original 1966 stereo mix in band's intended running order. The latter is different to the alternative stereo version used on Sign of the Three Eyed Men. The set also includes five unreleased mixes which are the producer/engineer Bob Sullivan's original stereo studio mixes. Recordings remastered and remixed in 2007 by the original producer Walt Andrus and presented in a luxury digibook limited edition of 5,000 copies with a detailed 16 page booklet written by band expert Paul Drummond.
