Warren Haynes has addressed the tragic death last week of Col. Bruce Hampton.

Hampton, a legend in the jam band scene since the 1970s, died on stage last week during the encore of a concert in celebration of his 70th birthday. Haynes was part of an all-star band performing with Hampton before a sold-out audience at The Fox Theatre in Atlanta, GA.

"We were devastated," Haynes said during an interview with Q104.3 New York's Ken Dashow. "There were 30 or 40 of us who were all on stage for the finale...We were honoring him and his music, and all his favorite people were there -- there was 5,000 people [in the audience], sold out. 

"It was the most amazing night of music," he continued, beginning to choke up. "Four hours, and then at the very end of the night, he just laid down on stage and he was done."

Hampton is best known for his Hampton Grease Band from the '70s and his Aquarium Rescue Unit in the '90s. The birthday concert featured Haynes, Blues Traveler's John Popper, Phish's Jon Fishman, Chuck Leavell and many other special guests, including teenage guitar prodigy Brandon “Taz” Niederauer.

Witnesses say they initially thought Hampton collapsed as a joke. Live for Live Music wrote that it appeared as though Hampton was "falling at the feet of his youngest star" while Niederaurer soloed.

Haynes' band, Gov't Mule, has a new album on the way. Revolution Come...Revolution Go will be available June 9.
