Joe Walsh is working with Mick Jagger, Ringo Starr, Keb Mo’, Jeff Beck bassist Tal Wilkenfeld and more. On what, exactly, Walsh isn’t yet saying but he’s posted a Facebook photo of him and the others, simply saying: “Cooking up something here at Capitol Records. I think you’ll like it.”

Also in the photo are producer Don Was, keyboardist Mike Finnegan, and legendary drummer Jim Keltner. Walsh has also posted a photo of himself with legendary soul singer/songwriter Bill Withers.

Bassist Wilkenfeld has provided the strongest clue this a serious new project. She posted, “Thursdays in the office are usually pretty mellow. Like today… when I wrote a song with Bill Withers, Mick Jagger, Keb Mo & Joe Walsh. LOL.”
