Live Dub Sessions Tour brings a rock/pop set to The Roof at Superior Ingredients, placing studio-minded performance in an open-air Brooklyn context. Adrian Sherwood, long associated with dub’s production grammar, approaches the stage as a mixing desk as much as a bandstand, shaping rhythm, echo, and space in real time. New York has been a key U.S. stop for dub and post-punk crosscurrents since the downtown scenes of the late 1970s. The result reads less like a conventional concert than a demonstration of sound as composition.
