The Constellations, hailing from Atlanta, have the distinction of being one of just a few bands lucky enough to grace the END Sessions stage on multiple occasions.  We were honored to have them back.  Listening to them is a true treat, because their choruses get stuck in your head, and lead-singer Elijah's voice hangs out like on old friend.

They've had songs featured on TV's Vampire Diaries and House, as well as the big screen comedy Horrible Bosses.

Southern Gothic, their 2010 debut album, features a guest spot from Cee-Lo, and judging by his Super Bowl appearance with Madonna, he's going places.

What I See and Felicia are tracks found on Southern Gothic, plus we got the treat of hearing a new track titled Side by Side.

Prior to the Not So Acoustic Xmas Warm-up at Amos', the guys from Middle Class Rut were kind enough to come by and tear up an END Session.  Even acoustically "New Low" is still a hard charging, boot stomping ride.  Comment below and let us know what you think.
