Bruce Hampton apparently died doing what he loved most.

The musician, called the "granddaddy of the jam scene" by the New York Times, collapsed on stage while performing at a tribute concert celebrating his 70th birthday.

The show, held at Atlanta's Fox Theater, was billed as "Hampton 70: A Celebration of Col. Bruce Hampton." It featured performances by members of Phish, R.E.M., Blues Traveler and other rock acts, as well as actor-musician Billy Bob Thornton.

In addition to music, Hampton acted in a few movies and TV shows, including "Tombstone" and Thornton's "Sling Blade," according to IMDB.
