Here’s a good rule of thumb: if Warren Haynes asks you to play at the Christmas Jam, you play.

That explains the fantastic lineup of musicians added to the initial lineup for the 26th annual event, hosted by Haynes, which will be held on December 13th at the US Cellular Center Haynes’ hometown of Asheville, NC. The lineup includes Vince Gill, Gov’t Mule, Billy & The Kids, Hard Working Americans, The Revivalists and Jason Isbell.

Billy & The Kids is a newly formed supergroup, featuring Grateful Dead drummer Bill Kreutzmann with Aaron Magner (The Disco Biscuits), Reed Mathis (Tea Leaf Green) & Tom Hamilton (American Babies, Brothers Past). If it’s anything like Kreutzmann’s Locknstep All-Stars’ performance at Lockn’ Festival, it’s gonna be one fantastic time.

VIP and Travel packages go on sale Thursday, October 9th, followed by an October 13th pre-sale, and an October 17th official on sale date. All of this information, and more, can be found on the official Christmas Jam website.
