Maroon 5

For a second there, it seemed like this Cali funk-pop crew's popularity was on the wane, but thanks to an increased profile as the host of reality talent contest The Voice, the falsetto-shrill modelizing frontman known as Adam Levine is riding high once more. Still, whatever you think of Levine, Maroon 5 are in fact extremely talented musicians who take their slick, radio-friendly rock very seriously and the boys know how to put on a great show.
