The annual Newport Folk Festival is happening this weekend at Fort Adams State Park in Newport, RI. The festival this year has some pretty heavy hitters including Phil Lesh, Warren Haynes, and Trey Anastasio among dozens of other acts.

On Friday, festival goers were treated to sets by both Warren Haynes and Phil Lesh and the Terrapin Family Band. During Phil’s set, his old buddy and frequent collaborator in Phil Lesh and Friends, Warren Haynes was invited to the stage.

Warren, Phil and the Family Band chose to cover a tune that will be 50 years old in January—”Almost Cut My Hair” by Crosby, Stills, Nash and Young. As you can imagine, Warren takes center stage with his blistering guitar work.

Thanks to Matt Frazier for the footage!
