The Black Keys are no strangers to Bonnaroo, having performed at the festival last year. The band brought home a number Grammy Awards on Sunday for their latest Nonesuch release, Brothers, including Best Alternative Music Album. Rolling Stone, covering the Warner Music Group Grammy after-party that included guests like Jay-Z and Beyoncé, declared: "The party's coolest guests, though, were unquestionably the Black Keys." They've got two sold-out shows ahead this weekend at The Chelsea at The Cosmopolitan: Saturday with Cage the Elephant and Sunday with Outkast's Big Boi.

The Black Keys performed "Howlin' for You" on Conan last night on TBS; you can watch that performance here:

The Low Anthem's new album, Smart Flesh, is out on Nonesuch one week from today, on February 22, and can be heard in full until then as an NPR First Listen at npr.org. The band kicks off their tour in support of the new album a week from Thursday in Washington, DC. In addition to Bonnaroo, their spring festival stops also include the New Orleans Jazz Fest and the Clearwater Festival.

Smart Flesh is available for pre-order in the Nonesuch Store with a limited-edition poster autographed by the band and an instant download of the album track "Ghost Woman Blues." You can watch the video for "Ghost Woman Blues" here:

Wanda Jackson is on tour in Austria this week and will return to the United States to tour starting next week at World Cafe Live in Philadelphia. She recently added several more dates to her schedule, extending the tour into April. In addition to Bonnaroo, Jackson's festival appearances include a stop at the Stagecoach festival in Indio, California. A Rock and Roll Hall of Fame member herself, Jackson will also participate in events surrounding the opening of the Hall of Fame's Women Who Rock exhibit.

Speaking of rock, watch Jackson rock out with the Third Man Band, featuring Jack White, the producer of her latest album, The Party Ain't Over, in a live performance of "Riot in Cell Block #9":

Jessica Lea Mayfield brought her tour with Justin Townes Earle to a close last night with a Valentine's Day concert at First Avenue in Minneapolis. She joins the Avett Brothers for three shows this coming weekend and then launches her own headlining tour next month. Mayfield was featured on NPR's Weekend Edition this past Saturday to discuss her recently released Nonesuch debut album, Tell Me, which was produced by The Black Keys' Dan Auerbach. You can watch a live performance of the album track "Sometimes At Night" here:
