As well as containing some vital hit singles like 'Jamming' and 'Three Little Birds' this is the most complete album I have heard by Mr. Marley. It is inventive reggae dealing with many issues from the deeply religious (without sounding sanctimonious) in 'The Heathen' and 'So Much Things To Say', through to political with 'Exodus', prophetic ('Natural Mystic') and simply humanitarian (One Love/People Get Ready). This music engages the brain and relaxes the body and strengthens the soul - not any easy feat, but here performed expertly.
