Bob Dylan wasn’t the best thing about this show (yeah, we said it) at MidFlorida Credit Union Amphitheater in June. While the folk luminary was the anchor and reason for Americanarama’s greatness, it would be foolish not to acknowledge the magical set by Wilco — which played to an already receptive crowd warmed up from a psychedelic set delivered by Morning Jacket, their performance preceded by a barefooted acoustic guitar-wielding Bob Weir. Superbills don’t come around very often and this one was once in a lifetime.
