Kesha Performs With New Band The Yeast Infection Amid Legal Turmoil, Shares Video of Nashville Concert

Instagram

She's back!

Kesha has been prohibited from recording new songs with producers other than her former collaborator Dr. Luke, with whom she has been involved in a more than year-long legal battle. But the 28-year-old singer continues to find ways to bring her music to the fans.

After touring earlier this year, Kesha has teamed up with a new, all-male band, The Yeast Infection. She performed with the group at a surprise concert at the Springwater Supper Club & Lounge in Nashville just before Christmas. The singer posted on her Facebook page over Christmas a video of their gig, during which she sang alternate versions of her hits "Blow" and "Timber" as well as a cover of Led Zeppelin's "Whole Lotta Love."

Kesha had also sung the latter classic track in September at a Los Angeles concert byThe Hollywood Vampires, the supergroup made up of Johnny Depp, Joe Perryand Alice Cooper.

Watch her video of her Nashville gig below (warning: Contains expletives).
