While everybody has heard the music of Bob Marley, the superstar of Reggae, few people know that it was Rocksteady that developed the buoyant rhythms, prominent bass pulse, soulful vocals and socially conscious lyrics that gave Reggae its power. This film features a mix of studio recording sessions at Tuff Gong Studios, rarely seen archival footage from the period and interviews with the performers at home or at places on the island that had had profound effects on their music and lives.
