KC and The Sunshine Band

If it seems like America’s obsession with butts is somewhat new (thank you, Nicki Minaj and Kim Kardashian), remember that KC and the Sunshine Band have been talking about the backside since the mid-1970s — well over a decade before even Sir Mix-a-Lot had his say. The funky Miami act came to prominence thanks to their disco tunes like “That’s the Way (I Like It),” "Get Down Tonight," "Boogie Shoes" and of course "(Shake, Shake, Shake) Shake Your Booty.” All of these songs are still as danceable as ever, which is why the act, led by frontman Harry Wayne Casey, is out on tour this year bringing the happy, nostalgic vibes to their fans.
