It's not clear what Joe Walsh is working on exactly, but the lineup he's assembled is certainly intriguing. The Eagles guitarist teased fans with a photo that indicates something very cool will be coming soon.

"Cooking up something here at Capitol Records," Walsh said on Facebook on Friday (March 8). "I think you'll like it." Pictured (from left) is blues guitarist Keb' Mo', producer Don Was, Mick Jagger, bassist Tal Wilkenfeld (known for her work with Jeff Beck), keyboardist Mike Finnegan, Walsh, Ringo Starr and drummer Jim Keltner.

Shortly after sharing this photo, Walsh uploaded a picture with legendary soul singer/songwriter Bill Withers. The pictures look to be taken on separate occasions as Walsh is wearing a different t-shirt. Still, that same day, Wilkenfeld wrote on her Facebook page, "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." An earlier picture of Walsh with War may also just be coincidence.

Walsh and Starr are brothers-in-law, and have worked together several times in the past. On March 27, Walsh will hit the road with Bob Seger, opening the Rock and Roll Never Forgets Tour.
