James Durbin/Kelley James

A former American Idol contestant (he finished fourth in Season 10), singer James Durbin is a musical chameleon of sorts. He sang in a country band and then segued into metal with Hollywood Scars. His new single, "Parachute," has much more of a power-pop feel to it and suggests he's finally found his musical calling. At tonight's show, you can expect to hear it and a slew of new material from the forthcoming Celebration. (Niesel)
