, gently strumming balladeer, frequent employer of vocal gibberish and wearer of pork pie hats, comes to Alltel following a familiar trajectory. Soon after high school, he busked in New York before shifting gears and heading West and settling in San Diego. In the early 2000s, after hooking up with a djembe player (of course), he conquered the local coffeehouse scene and expanded his base to LA. In 2002, he signed to Elektra. Since then, he's released three albums, collaborating with the likes of producer John Alagia (Dave Matthews Band, John Mayer) and the hit-making songwriting trio the Matrix. With those albums, Mraz has cultivated a breezy, Jack Johnson-style folk-pop that the kids can't seem to get enough of. Lyrically, he's been fairly sex-obsessed (“I can taste you all over my face” was one of the more unsubtle moments on his sophomore album), though with his latest release, “We Sing, We Dance, We Steal Things,” despite occasional lines like “you make my slacks tight,” he seems to be focused more on sounding sexy. So beyond his chart-topping acoustic ditty “I'm Yours,” his material mostly tilts toward more '80s blue-eyed soul territory. With the punk-pop act Plain White T's
, famous for their weepy ballad “Hey There Delilah,” opening the show, look out for a lot of sing-a-long swaying.
