Gov’t Mule and Yonder Mountain String Band teamed up for a special co-bill (along with opener Marcus King Band) at Red Rocks last night following Mule’s lengthy run with Galactic that yielded a number of collaborations.

On this night, it was a fitting Gregg Allman tribute that brought all band members together as Mule first welcomed Marcus King to close their set with “Whipping Post” after playing the set sans guests until that point.

In the encore, Mule debuted their version of “Melissa” with King as well as Yonder’s Dave Johnston, Adam Aijala, Allie Kral and Jake Joliff. The ensemble stayed on for a jam into “Mountain Jam” before returning to the Allman classic.
