Garth Brooks has been slumming this summer. Sort of.

The country superstar has embarked on a series of "Dive Bar" concerts, and the next one is in Texas. He performs Sept. 23 at the historic Gruene Hall. But you can't buy tickets.

The only way to get in is to win passes through country radio. And you must be at least 21 years old.

Brooks' new album, "Fun," is due out soon. It's preceded by a single called, you guessed it, "Dive Bar."

Gruene Hall is in New Braunfels and just under three hours away from Houston. Road trip!
