Eagles guitarist Joe Walsh is working on a new album of obscure R&B and blues songs with Dr. John and a host of other celebrity pals. The album will also feature collaborations with Robert Randolph, Keb' Mo' and Jeff Beck bassist Tal Wilkenfeld. Walsh tells Billboard.com, "Half of it is original, and half of it's old Howlin' Wolf or John Lee Hooker. I told everybody to bring a song in and everybody did, be it an old blues song or some idea. We went through some old Stax records from, like, the Otis Redding days, Sam & Dave stuff that were just album tracks, and did our version of a whole bunch of stuff."
