R&B singer Charlie Wilson has been gracing stages since the '60s, but this is no nostalgia act. In fact, he's getting some of the best concert reviews of his entire career. His energetic, party-like concerts combine the smooth R&B style he's largely adopted over the last decade with the straight-on funk that first made him and his brothers famous in The Gap Band. Tickets for his tours are snapped up by generations of fans, with those from The Gap Band's heyday joined by newbies drawn in by his contemporary material and his close associations with current stars like Snoop Dogg and R. Kelly. Wilson's recording career continues to be as vital as his concerts. His 2013 album, Love, Charlie, reached No. 4 on the Billboard 200 chart, marking his second album to reach the Top 5 in four years, and his 2010 ballad "You Are" was nominated for two Grammys.
