Gov't Mule

Some of these albums started as studio recordings and turned into something completely different the moment a live crowd showed up.

These are projects that don't include the keyboardist's two main bands, the Allman Brothers and the Rolling Stones.

His former Allman Brothers Band collaborator Derek Trucks appears on three songs.

Warren Haynes and band return with Billy Gibbons, Billy Bob Thornton and more quality blues rock.

Leader Warren Haynes describes the upcoming LP as "very ambitious."
