There were many obscure garage bands in the mid-'60s who released limited editions of all-cover albums to be given away at gigs and school. Most of these albums were virtually worthless except as time capsules, but there were a few scattered exceptions that proved the rule -- LPs of this kind by T.C. Atlantic and the Litter became valued collector's items. The Dimensions were another example. Nothing is known about this Chicago college group, whose derivative, but exciting, album achieved a much greater audience when it was reissued for the '60s collector audience in the '80s. ~ Richie Unterberger
