He may be all over country radio right now with his “Put You in a Song,” but now you have the chance to literally put Keith Urban in your own song. As in … he will be providing a guest appearance on one of your recordings. And then, as if that isn’t enough, you’ll be opening for him at one of his big shows. Then there’s about $20,000 in guitars and guitar merchandise and the chance to produce a three-song EP and have your song on iTunes. First, though, you do have to win the Guitar Center’s contest to find the most talented — but unsigned — new artist out there. “I think we’ve all heard someone whose musical talents blow us away,” Urban said, “and sometimes all that stands between their garage and an arena is a chance.” You have until Nov. 30 to enter. There are already more than 1,000 entries. But do not let that discourage you, because you could be the one that goes from garage to arena by January.
