Black Pearl Sings

Who “preserves” gritty Americana music like “No More Auction Block”—the black convict whose forebears have sustained the song since slavery or a white Ivy League folklorist, “field recording” it for posterity? This two-actress Depression-era drama explores that conundrum. Crystal Fox’s soulful, gutsy solo vocals are outstanding. W 12:30 & 6:30pm; Th, F 8pm; Sa 2 & 8pm; Su 2pm. Through 5/9. $15-$36.
