Childhood friends and brothers in music, Dan Auerbach and Patrick Carney have enjoyed critical and commercial acclaim as The Black Keys, delivering swampy blues-rock to the masses with hits like “Gold on the Ceiling” and “Lonely Boy.” After a hiatus which both members needed in order to recharge, the Keys are back with Let’s Rock, a high-octane set that showcases old harmonies and new growth. Hit The Chelsea at The Cosmo for a rockin’ good time.
