Like Sun Ra's Arkestra and John Coltrane are to jazz, The Mystic Revelation of Rastafari are to reggae - the ultimate expression of roots music and Rastafarian ideology in reggae music, music functioning at a high level of spiritual consciousness combined with an equally avant-garde and forward-looking approach to sound. The group's stunning, unique and groundbreaking 1972 album 'Grounation', a mighty conceptual triple-album (the first ever reggae triple!) is, similar to Marvin Gaye's 'What's Goin' On', a definitive all-encompassing cultural statement of its time and place. A sprawling album of raw and unique cultural expression that combined Rastafari consciousness with deep spiritual jazz music - an absolute and essential classic of reggae music.
