The five-piece iteration of the band took to the stage shortly after 8 p.m. on Friday night and opened with “Will the Circle Be Unbroken.” It’s a song often reserved for the end of the night. But in this case, it set forth the evening’s familial tone as front man Rawlings lead the newest lineup of his ever-evolving Machine through a two-and-a-half-hour old-time music marathon.
