Durty Dub brings live improvisation and a DJ-minded approach to the same set. Afro-Caribbean rhythms, ballads and distorted guitar all figure into the band's description of its sound. Its cover repertoire reaches from Katy Perry and John Lennon to WAR and Nirvana. Original music sits alongside those reworked tunes. The One Stop hosts Durty Dub at 55 College Street. Music starts at 10 p.m., and this show is 21+.
