Courtesy of Christmas JamEx-Allman Brothers Band guitarist Warren Haynes has unveiled details of the 29th annual edition of his star-studded Christmas Jam benefit concert, scheduled for December 9 at U.S. Cellular Center in Asheville, North Carolina. This year’s show will include a special appearance by Heart frontwoman Ann Wilson, who’ll join Haynes’ band Gov’t Mule for a portion of their set.

This will mark the first time Wilson will perform at a Christmas Jam. In August, she teamed up with Gov’t Mule for a special performance at the Lockn’ Festival in Arrington, Virginia.

The lineup for the 2017 Christmas Jam also features Les Bros., which includes founding Allman Brothers Band drummer Jaimoe and other Allmans alumni; Phish‘s Trey Anastasio and his side group Classic TAB; The Avett Brothers; Blackberry Smoke; and more.

The concert, which is expected to run for over seven hours, will benefit the event’s longtime beneficiary: the Asheville Area Habitat for Humanity charity. Tickets go on sale to the general public on Thursday October 26, while pre-sale tickets and VIP packages will be available starting this Thursday, October 19.

In conjunction with the main Christmas Jam show, a number of related events will be held in Asheville around the date of the benefit concert. “Xmas Jam by Day” gigs will take place at the Asheville Music Hall and that venue’s affiliated club, The One Stop, while an art and photography show will be hosted by a local gallery.

In addition, the annual “Before the Jam, Lend a Hand” event will bring fans, artists and staff members together to help build houses funded by money raised by the Christmas Jam.
