Warren Haynes, Allen Woody, and Matt Abs—guitar, bass, and drums respectively of none other than the Allman Brothers—formed this trio in the late 90s. With a dozen albums to their name, we have been lucky enough to have Gov’ Mule three times on the Azkena Rock Festival stage in their barely 15-year career. Three unforgettable concerts that make them worthy of this star in the Rock Walk.
