P.O.D.

They've been a band — and a vital one at that — for more than 30 years. But ask rock icons P.O.D. what still inspires them after all this time, and they'll tell you they still operate as if they're perpetual underdogs. Yes, with every new album they release, with every show they play, these musical lifers still feel they have something to prove. "We're still here and we're still creating some of the best music we've ever made," says guitarist Marcos Curiel. "When it comes to heart, grit and soul, P.O.D. is your band." Adds vocalist Sonny Sandoval: "We're always still proving who we are — always having that punk-rock mentality."
