The Black Keys' new album, Turn Blue, is out now on Nonesuch Records. In celebration of the release, the band performed on Saturday Night Live this past weekend; the Late Show with David Letterman last night, including a special outdoor concert for Live on Letterman, which you can watch below; and returns to The Colbert Report on Comedy Central tonight. The band spoke with NPR's Steve Inskeep on Morning Edition, which you can hear here. Band member Patrick Carney will be conducting a Reddit AMA on Wednesday, May 14, at 3 PM ET, so stop by then to ask him anything. Tickets for the band's fall North American tour began this morning for Citi card members and fans who pre-ordered Turn Blue in the Nonesuch Store and the band's site. General on-sale begins this Friday.

Produced by Danger Mouse, Dan Auerbach and Patrick Carney, Turn Blue has been met with critical acclaim around the world.

Rolling Stone gives the album four-and-a-half stars. Reviewer David Fricke calls it "the best, most consistently gripping album The Black Keys have ever made … as apocalyptic, in its way, as that Clash epic [London Calling]: loaded with risk, distress and payoff." Read the complete review at rollingstone.com.

The Associated Press says Turn Blue is "the sound of a band operating at the peak of its power ... [Their] evolution from a simple guitar-and-drums duo to a fully formed, Grammy Award-winning stadium rock act is remarkable." You can read the AP review at washingtonpost.com.

In the UK, where Turn Blue was released yesterday, it was named Album of the Week by the Guardian, the Times, Metro, and the Independent, whose Andy Gill gives the album a perfect five stars and calls it "a post-modern blues-rock marvel." Guitarist gives it five stars as well, citing its "slow, sleazy and soulful grooves. Turn Blue is home to some of Auerbach’s most considered and inventive playing to date."

The Daily Mail gives it a perfect five stars as well, saying: "An inspired blend of blues, soul and stadium-sized hooks have made this Ohio duo the world’s best rock band."

Mojo, the cover of which is sporting the band this month, says: "Turn Blue is a deeply satisfying record with richer textures and sharper pop hooks, and underlines the fact that The Black Keys are the most vital rock band in the world right now." Uncut names Turn Blue Album of the Month, saying: "Turn Blue turns out to be The Black Keys’ sneakiest, subtlest and most seductive album."

The Clash says: "Pushing creative boundaries for their eighth release, The Black Keys fuse layers of tenacious funk with serrated Neil Young-like guitars and hypnotic allusions of psych. Turn Blue is pure searing sexiness, hotter than a Nashville afternoon. Their best yet."

To pick up a copy of Turn Blue, head to your local record store, iTunes, or the Nonesuch Store, where CD and vinyl orders include a download of the complete album at checkout; MP3 and FLAC lossless files are available to purchase there as well.
