Planet Earth is a Mighty Diamonds (curiously named The Diamonds on release)vocal album from 1978 and Planet Mars Dub (credited to The Icebreakers & The Diamonds) was the track for track dub counterpart album released in the same year. Rather than have one album come after the other in traditional "2 on 1" fashion, this release sequences the vocal versions followed directly by their dub to create a showcase / discomix / 12" style, that gives listeners a chance to hear the vocal and dub back to back andexperience the full extendednature of these tunes. Planet Earth has never been released on CD and Planet Mars Dub is increasingly becoming more difficult and expensive to find and this is the first time that these two albums have been presented together. This is a jam packed disc with over 74 minutes of classic roots reggae. Sleeve notes are providedby well-respected reggae expert and journalist John Masouri. Singers and Players include Sly Dunbar on drums, Tommy McCook on Sax and "blazing horn arrangements", Earl "Chinna" Smith on guitarwith production by Karl Pitterson at Compass Point Studios, Nassau, Bahamas.
