Although this brief album by the Heptones ? Rainbow Valley ? has some delightful tracks ("Tougher Than the World," "Head On Straight," and a remake of Naggo Morris' "Susu Pan Rasta"), it feels like it lacks any clear vision and proves a far cry from their classic-'70s work. The decision to record a version of Tommy James' "Crystal Blue Persuasion" was certainly ill-advised, since the sugary original is here rendered as flat confection.
