Thirty years deep in an inestimably influential career, the singer, songwriter, and guitarist Thurston Moore has pulled off a rare trick: turning punk, art-rock, and experimental music into a work of authentic pop sincerity. No so-called indie band has permeated mainstream consciousness as deeply as Moore’s iconic Sonic Youth, the standard-bearers of avant-garde guitar theatrics and passionate disaffection. Now one of the greatest guitarists of his generation visits Reynolds Theater to perform songs from his acclaimed new solo album, Demolished Thoughts — produced by pop chameleon Beck, where Moore’s forays into acoustic folk are “as immediate and form-warping as [his] work with Sonic Youth” (Pitchfork).
