The Person Who Filmed the Glastonbury Concert Footage Is Actually a Very Famous Musician
Watching the film, it's clear that Cooper and Gaga were performing at actual concerts. Many scenes include festival footage, where Bradley performs for thousands of people, including Coachella, Stagecoach, and Glastonbury. Cooper said that himself, the film's cinematographer Matthew Libatique, and two others were the only ones to travel to the Glastonbury Music Festival in England. He had four minutes ahead of Kris Kristofferson to play on stage. One of the cameramen filming on stage with him was Lars Ulrich, drummer and cofounder of Metallica. Cooper asked if he'd be willing to film his performance, and he obliged.
