The Miami-based KC and the Sunshine Band scored again and again in the '70s with their spirited, ultracatchy pop-disco. As this two-disc set makes clear, hits such as"Get Down Tonight,""(Shake, Shake, Shake) Shake Your Booty," and"Keep It Comin' Love" remain utterly delightful. 25th Anniversary Collection also places emphasis on lesser-known prestardom singles such as"Queen of Clubs" and"I'm a Pushover." Its only real flaw is in a certain too-completeness that leads to the inclusion of three versions of the ballad"Please Don't Go" and a couple of weak Motown covers (KC's own Detroit pastiche,"Who Do Ya Love," is much more successful). Still, it's hard to imagine a more definitive look at these party kings.
