“Ho-hum,” you say, “another Americana duo.” Then you hear The Brother Brothers harmonize and realize you’re in the presence of greatness. Brother David’s on cello and guitar, brother Adam plays a five-string fiddle, and together they range from Appalachia to Eastern Europe on the wings of those fantastic voices. Caroline Cotters opens the 8 p.m. show at One Longfellow Square (181 State St., Portland). Tix: $16 (all ages). 761-1751. onelongfellowsquare.com. Meanwhile, at Hannaford Hall (USM’s Portland campus), the California Guitar Trio and the Montreal Guitar Trio join forces to perform original compositions and a rad selection of prog rock, jazz, classical and world music at 7:30 p.m. Tix: $43-$47 ($18 students). 842-0800. portlandovations.org.
