Boston-based indie folk quartet Darlingside brought their signature superpower harmonies to Provincetown. Darlingside draws frequent comparisons to late-sixties groups like Crosby, Stills & Nash, Simon & Garfunkel, and The Byrds, yet their penchant for science fiction and speculative futurism shows their aesthetic to be anything but "retro." NPR Music describes the four friends’ collaborative work as "exquisitely arranged, literary-minded baroque folk-pop" and pronounces their album Extralife "perfectly crafted."
