Mexican psych duo Lorelle Meets the Obsolete typically traffic in delirious, reverb-heavy psych, the kind of music that shimmers miragelike on the horizon. (Their excellent 2011 album On Welfare explored that drowsy darkness to chilling results.) So the trumpet-like feedback-blast and galloping tempos that open “Sealed Scene,” from their latest album, Chambers are a bit surprising. But the band — Lorelle Quintanilla and Alberto González, aka “The Obsolete” — harness this energy immediately, riding it like a runaway horse through a song that endlessly whipsaws from one peak to the next. It’s a fantastic roar of a song, blistering and exhilarating.
