It started with the positive proclamation “I’m grateful to be here!’’ and continued with requests for a group hug. Then there was a screen silhouette of people giving high-fives and an order for audience members to sing to their neighbors.
If there were any doubts about Jason Mraz’s unwavering good mood, last night’s show at the Bank of America Pavilion should have killed them. The pop singer, whose single “I’m Yours’’ has been sugaring up the airwaves for months now, was thankful, cheery, and lovey-dovey for two hours straight. It was difficult not to love him back, especially with that voice. Even if you eye-roll his cookie-cutter radio tunes, a live performance proves that the West Coast rocker is a songbird. The sleepier tracks from his latest album “We Dance, We Sing, We Steal Things’’ are juicier live, when he can show off that range and his almost uncanny pitch-perfect clarity.
