Marie & Rosetta is a stirring and often rousing musical biography of the life of gospel popularizer (and rock and roll predecessor) Sister Rosetta Tharpe. The work focuses on Tharpe’s relationship with her protégé Marie Knight, who Tharpe pulled from Mahalia Jackson’s backup choir and with whom she performed for three years. Kecia Lewis and Rebecca Naomi Jones as Tharpe and Knight, respectively, belt out the music true to its origins. Playwright George Brant struggled to find an ending, and it’s a little distracting the way the two stars have to mime playing their piano and guitar to (admittedly excellent) off-stage accompaniment, but those few awkward minutes do nothing to diminish the impact of the songs or the story. Directed by Neil Pepe. Runs through October 2 at the Atlantic Theater Company’s W. 20th Street house, NYC.
