Preach it! The Black Keys are back and the promotional machine is in full swing! The duo recently debuted their video for their hit single 'Fever' and they're also now streaming their 'Turn Blue' album ahead of its May 13 release.

As for the video, it finds frontman Dan Auerbach as a televangelist, getting a little sweaty while preaching the word of the lord while drummer Patrick Carney looks on. As the clip moves forward, the audience gets more and more pulled in by Auerbach's preaching and the clip ends with some good old fashioned faith healing. The video can be seen above.

As for the 'Turn Blue' album, the Black Keys are giving fans an early preview via iTunes. You can listen to the full disc at iTunes, and you can pre-order 'Turn Blue' there, as well. The band also has a pre-order site where you can get the standard edition of the album as well as bundle packages here.

For fans looking to catch the Black Keys, check them out this weekend when they appear as the music guests on 'Saturday Night Live' with guest host Charlize Theron. The 'SNL' episode airs May 10 on NBC at 11:30PM ET/PT.
