The Black Keys came on stage at US Airways Center last night in front of a light blue curtain with red, velvet stage drapes with gold trim on either side. After the fourth song, during a tension-building burst of distorted guitar noise, the curtains dramatically dropped, and the band launched into the opening guitar riff of "Same Old Thing." Behind the band were a series of screens that shifted and moved on unseen tracks and featured various visuals and projections of the performance.
It wasn't anything new -- the first time I personally saw the whole "screens moving around and coming together to create trippy visuals" thing was at Radiohead's King of Limbs tour stop in Colorado in 2012. But the way the Black Keys' set incorporated these screens, squares that would drift apart and then occasionally move together to form one giant square and so on, was absolutely spellbinding, much more so than Radiohead's use of it a few years later.
In a way, that's a perfect analog for the Black Keys in general.
