Perpetual Groove has been a staple of the Jamband scene for almost 15 years now. Their studio recordings have been received with success, but it is really their live shows and dedicated fans that have kept P-Groove on top of the scene and riding that momentum into their sophomore decade. Based out of Athens Georgia, P-Groove has achieved international success and are staples of the festival world.

Band of Skull's new record, quite an improvement over their previous full-length album (2009's Baby Darling Doll Face Honey), showcases a more emotional and lyrically complex side of the band. Entitled Sweet Sour, the album lives up to its name.
