Tumbledown Saints, a blues band from Maine that plays original music as well as songs by the masters, performs at Pedro O’Hara’s, 34 Main St., Lewiston, Friday, Aug. 4, from 8 p.m. to midnight. Promotional material describes the band as eclectic, danceable, energetic and just on the edge of flying out of control. Formed in early 2017, the band reunites three members of Mama’s Boomshack – a funk-and-soul band that kept booties shaking on the dance floor for more than six years – and adds a pair of new wild cards to the deck to keep things interesting.
