If we had to put our money on two acts that are totally revolutionizing pop-punk, it'd be State Champs, of course, and a band hailing from across the pond, Neck Deep. If you haven't listened to them before, well, what the heck do you think you're doing?

You might've caught them at Warped Tour last year. If not, know that they're actually on tour with our boys in State Champs right now. At a recent stop in Atlanta, the Neck Deep guys decided to delight a few lucky fans with an intimate, acoustic performance. 

The best part? They covered the old school Fall Out Boy tune, "Grand Theft Autumn / Where Is Your Boy." Watch it above.

When you're done there, watch this recent interview with FOB as they dissect their "Uma Thurman" single and that now infamous Munsters-sample.
