Lenny Kravitz + Raphael Saadiq

Yes, we may laugh at Lenny Kravitz, his ridiculous rock-star stylings and the fact that his own website describes him as a "legendary artist." But Kravitz has sold 40 million records worldwide—some of them truly great. (C'mon, you really didn't like "It Ain't Over 'Til It's Over"?) For his first U.S. tour in five years, he's teamed up with consummate soulman Raphael Saadiq. Expect to work up a sweat dancing to these superstars' deliciously retro grooves.
