Let's be honest: the Black Keys never really suited stadiums. Anyone who saw their intimate and incendiary early performances in the Kings Arms or the Powerstation knows their 2012 Vector Arena show was cold and impersonal in comparison, despite drawing heavily from El Camino's mainstream-smashing accessibility.
The question is, if you're a stadium-sized band and you don't want to rock stadiums any more, what do you do next?
For Akron duo Dan Auerbach and Patrick Carney, the answer is to turn off the amps. Turn Blue's mellow change of pace feels like a reaction to El Camino's stadium-filling success, a slower record that relies on the subtle and moody blueprints of producer Danger Mouse to get its point across.
That means those electrified guitar riffs that made feisty El Camino tracks Lonely Boy and Gold On the Ceiling so enjoyable are gone. There are still great tunes here - they're just packaged differently. It's Up to You Now has a throbbing bass rasp, skittery drum patterns and a ghostly howl delivered by Auerbach.
Year in Review is a slender melodrama with Auerbach's girl problems detailed over spooky choirs. And Fever has a classic Carney drum beat and a shimmering electro throb as a tired-sounding Auerbach moans, "Just go ahead and kill me".
