Alison Krauss and Robert Earl Keen have been added to the star-studded lineup for the July 6 Waylon Jennings tribute at ACL Live.

“Outlaw: Celebrating the Music of Waylon Jennings” comes two days after Willie Nelson’s Picnic on July 4 at Circuit of the Americas, with many of the Picnic participants joining in. Previously announced performers include Waylon’s widow, Jessi Colter, and son, Shooter Jennings, along with Nelson, Kris Kristofferson, Eric Church, Toby Keith, Kacey Musgraves, Sturgill Simpson, Lee Ann Womack, Ryan Bingham, Jamey Johnson, Chris Stapleton and Billy Joe Shaver.

Additional floor seats, at $275, have just been added, along with standing-room-only floor tickets at $175. Previously available tickets ranged from $150 for balcony seats to $400 for VIP mezzanine. Tickets are available at the ACL Live box office, by phone at 877-987-6487 or online via

“This incredible lineup of artists is a testament to how Waylon influenced musicians everywhere,” says Keith Wortman of Blackbird Presents, which is putting on the show in conjunction with Colter, ACL Live’s Freddy Fletcher and Mark Rothbaum, Nelson’s manager. Grammy-winning producer Don Was and Buddy Cannon, producer of several recent Nelson records, will serve as co-music directors of an all-star house band.

Those who purchase tickets for the show also have the option to buy tickets to an official after-party that includes open bars and appetizers backstage at the venue. All income from the $100 after-party tickets will go to the United Way for Greater Austin and will be earmarked victims of the May floods in Central Texas. Donations also can be made via the United Way website.
