If you had no knowledge of Maroon 5 and tuned into the Super Bowl halftime show last night, you’d have thought Adam Levine was a solo act. That’s a shame, especially since I’ve seen Maroon 5 live, and the only good part of the show is lead guitarist James Valentine. Mr. Valentine is the extremely well-dressed, long-haired gentleman who can play. He’s often lost in the shadows of Levine, who is less than generous to his band. When I saw them perform live at The Forum, his band was barely visible behind the ridiculous light show and stage placement. If you’re curious what it looks like when a lead singer is generous to his fellow musicians, go see Bruce Springsteen live. I realize that no one compares to The Boss, but given his performing prowess, one might expect that he too would steal the spotlight at the expense of his band — and he does the opposite.
