Of all the impressive details in singer/composer Sami Stevens’ bio, two stick out: lead vocals in a “faux Italian 70’s soundtrack band” (Tredici Bacci) and in a “prog soundtrack group” (Morricone Youth). Her latest project, with backing group the Man I Love, is a jazzy R&B affair. The Maine native (now based in Brooklyn) performs pre-fireworks at Blue (650 Congress St., Portland) at 7 p.m. Free (donations encouraged; all ages). 774-4111. portcityblue.com.
