Soap fans watched Jonathan Jackson grow up as Lucky Spencer on General Hospital; now he's all grown up and playing a rocker on ABC's new drama Nashville, and we have an exclusive sneak peek!

Jonathan, now 30, who calls his character Avery Barkley a "rebel," says of the show, "One of the coolest things about being involved in Nashville for me was that I'm a musician in real life and an actor, and I get to play a character who is a musician."

He adds, "When we're performing on stage, I'm doing the singing, and playing the guitar, and it's like a dream come true, really."

"There's no black and white situation where it's easy to say, 'Well, he's the bad guy, and he's the good guy,'" Jonathan promises of the show, which also stars Friday Night Lights and American Horror Story Emmy nominee Connie Britton, and Heroes star Hayden Panettiere.
