For the latest issue of Rolling Stone, Patrick Doyle flew to Cleveland to catch the Black Keys open their new arena tour. "The 90-minute set proves how comfortable the Keys have become as an arena-rock act, blending the raw power of their early albums with breakthrough singalongs like 'Howlin' for You.'" he wrote. "The stage setup is the Keys' biggest ever: 17 LED screens playing low-res videos and psychedelic images, a 16-foot 'hypno-wheel' that appears for the encore ('Turn Blue'), and vintage crate lights that give things a Seventies arena feel." Here, see how this unusual stage setup came together in a gallery of photos documenting the day-long assembly process and the roaring show that ended the evening.
