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.
