Given the name, news that there were quite distinct incarnations of The Uniques might have you scratching your head, given the notion that unique suggests a singular and unmatched entity, but that's par for the course for reggae vocal groups.
In 1966 Slim Smith and Franklyn White from The Techniques, joined Roy Shirley to create a group that cut a few ska sides before disbanding. A second incarnation, with Smith, Lloyd Charmers, Jimmy Riley and occasionally Cornel Campbell ran from 1967 to 1969, recording among other tracks, covers of Stephen Stills' For What It's Worth (rebadged as Watch This Sound), and Gypsy Woman (Curtis Mayfield).
Given a rating as the pinnacle of Jamaica's harmony trio genre (the consummate Jamaican vocal group, a trio of singers so sublime that virtually all others pale in their presence) and a relatively slim discography, the listing below is meant to deliver a checklist that will line up the available albums with the singles which would, at least from where I'm sitting, represent the pick of the crop of recordings.
While the group folded in 1969 and Smith died in 1973, you'd possibly rule out any possible reunion in the wake of The Wailers' international success, but the group name was revived twice. First, by Riley and Cornell Campbell in 1977 (the album Give Thanks). Later, Al Campbell joined Cornell and Riley to cut The Uniques. Significant. File under: Reggae vocal trios
