Whenever Nick Waterhouse rolls down the freeway for a hometown gig, it’s usually a big occasion. The surf-loving, smooth singing, retro R&B/soul maestro has become a favorite of the hip set with his throwback sound. But, there’s a lot more to the Santa Ana native than that. Always working, the singer/songwriter’s relentless efforts in the studio and on-stage have seen his profile grow in recent years. His work on independent labels usually wouldn’t garner so much as a sniff to license his music, yet Waterhouse’s music continues to soundtrack Lexus ads and the like. Before he heads to Europe, the 31-year-old has one last show at home, which will remind folks that no matter where he travels, Waterhouse will always be one of us.
