Digitally remastered and expanded edition of this 1978 album from the Reggae trio which includes the Dub album as bonus tracks, Planet Earth is a Mighty Diamonds (curiously named The Diamonds on release) vocal album 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 and experience the full extended nature 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 provided by well-respected reggae expert and journalist John Masouri.
