All musicians evolve and at some point may lose fans who expect them to keep playing what they want to hear. The Beatles came from a simple first record to Sgt. Pepper and many people disliked the change. In an era where true rock and roll music is lacking Grace Potter and THE Nocturnal are exciting and I suspect will continue to be. Exciting and meaningful music comes at a cost, how many of our favorite bands broke up over differences we could not understand. No one has said the band is done and until then let's keep supporting them. If they do part ways we can all say thank you for the magic and best of luck to all.
