Cage the Elephant could be on the cusp of something huge. Over the last couple years, they've gone from a relatively unknown alternative/punk/blues band from Kentucky to signing with EMI records, playing at South by Southwest, and last month they appeared on The Late Show with David Letterman. They've got a radio ready sound, with catchy, hook driven songs like the already popular "Ain't no Rest for the Wicked". Now, they're setting off on a headlining tour, which makes a stop at Revolution Live on October 7. Tickets go on sale tomorrow via Ticketmaster.
