The Black Keys have kicked off their North American tour, offering the home-state crowd in Cleveland their "most superlative-sapping local performance to date," raves the Cleveland Plain Dealer. "Eardrums were ravished. Minds were blown. And when singer-guitarist Auerbach and drummer Patrick Carney finally made their exit, sweat-soaked and utterly spent, it was no small wonder that the downtown skyline was still standing." Pat and Dan's fathers appeared on WKSU radio to offer their unique perspective on the band.
