Nashville's JEFF The Brotherhood brings quite the heavy punch for only being made up of two dudes who have a clear love for all things garage rock, cheap beer, and sweat. This particularly track, "Sixpack," finds the duo teaming with Dan Auerbach, of The Black Keys. He served as the producer for this joint, which will appear on the Brotherhood's upcoming Hypnotic Knights EP and LP. The former drops May 22 and is sounding solid so far. Stream "Sixpack" below.
