In a new interview with Relix, Derek Trucks recounts the moment when he found out the news that his uncle and founding Allman Brothers Band drummer Butch Trucks had committed suicide.

“You’re just fucking sideswiped,” Trucks said, calling the whole ordeal a “shocking, dark situation.”

“No one saw any of that stuff coming, so it was, and still is, a lot to unpack. My dad, Butch’s brother, was on the road with me when it happened. He was just shocked and pissed off. You have all these emotions and you just don’t know how to process them,” he added.

Trucks also described that first night playing following Butch’s death, with Tedeschi Trucks Band playing in St. Louis that night. The group opened with “Statesboro Blues” that night as a tribute to Butch, as Trucks recalls that’s the first song he ever played with his uncle on stage. “It’s also the first tune on At Fillmore East,“ he added. “The first tune that a lot of people heard of the Allman Brothers—and it seemed right.”
