Contrary to popular opinion, not all noise-based music is created equal. Sure, Los Angeles art-spaz quartet Health sounds and looks like it's having a collective seizure onstage, but the band also elevates chaos into a refined, almost symphonic art. And even while Health scrapes your face raw with blasts of funnel-cloud guitars and keyboards, the band's execution betrays the grace that ultimately makes it so exceptional. Don't make the mistake of pigeon-holing Health with other, less imaginative purveyors of dance beats and Nintendo-core bleeps. Health does touch on those things, but the strength of its writing the strength and uniqueness of its identity refuses to succumb to easy categorization. With Past Lives, Picture Plane, Pregnant. All ages.
