“Every little thing, is gonna be alright… We’re just gonna do this for fifteen minutes!” Jason Mraz & His Superband closing out the first of two sets, channeling a bit of Bob Marley. Which seemed quite appropriate, given his fun and optimistic “an evening with…” style show at Ironstone Amphitheatre on Sunday night, marking his only Northern California show on this tour. Early in the first set, he advised the audience, “you are permitted to sing… you are invited to sing… you are practically obliged to sing…” The audience accepted this challenge and most were up on their feet dancing and singing throughout the night. Mraz certainly has a distinct outlook on life that he carries with him and that is contagious with his fans (who span all ages, gender, and culture), and I’d have to say it was certainly the most joyful show I’d seen out of dozens at this beautiful venue, and that’s saying a lot.
