Booker T. & the M.G.'s
The name Perpetual Groove indicates a stylistic form for the veteran jam band. You hear the name and imagine long songs segueing through jams from one to the other. In a sense, Perpetual Groove could define many jam bands, but with PGroove, you get the name, and an assortment of various musical tastes and styles that careen from the stage like a robotic factory on overdrive.
