The Black Keys rocked Lollapalooza 2012 on Friday night in Chicago.

Following an introduction by Chicago mayor Rahm Emanuel, The Keys delivered an energetic 90-minute performance at Grant Park, a stop on their “El Camino” tour.

MTV reports there was nothing flashy about their set, and they kept on-stage banter to a minimum, preferring instead to just keep their heads down and blast.

And they accomplished that feat in spades. Songs like "Howlin' For You" and "Next Girl" snarled and slunk, "Gold on the Ceiling" was a supercharged stomper and "I Got Mine" simmered for what seemed like an eternity before finally combusting.

What the dynamic duo (plus backing band) lacked in showmanship, they more than made up for in sheer volume, flexing some serious muscle on tunes like "Little Black Submarines," "Your Touch" and "Lonely Boy."

The Keys head to Europe for a series of dates starting August 9 at the Way Out West festival in Gothenburg, Sweden.
