A trailer is out for May It Last: A Portrait of the Avett Brothers, the upcoming documentary from unabashed fans Judd Apatow and Michael Bonfiglio. You can watch it above.

May It Last was shot over more than two years, and chronicles the recording of the Avett Brothers' Grammy-winning 2016 album True Sadness. Rick Rubin produced the record, and spawned the initial idea for the documentary, Apatow told Filmmaker Magazine

Apatow, who financed the film himself, only recently dipped a toe into non-fiction projects after directing a string of huge box-office hits. He became an instant fan after seeing the Avett Brothers perform with Bob Dylan at the Grammys, while Bonfiglio says he was first hooked after hearing "Live and Die" from The Carpenter during the closing credits of Apatow's This is 40.

"I fell in love with that song and decided that would be an appropriate song to end This is 40 with," Apatow told Filmmaker. "Then at some point, Rick Rubin called and said, 'They are about to start the next record. It might be a fun documentary to follow them while they did that.' That was when I called Michael, who had directed an episode of the TV show Iconoclasts with me and Lena Dunham. Since I was a kid, if I liked an artist, I always wanted to interview them or get near them so I could learn something or be inspired in some way."

May It Last: A Portrait of the Avett Brothers will be screened in more than 250 theaters nationwide on Sept. 12. Visit the band's website for a list of theaters participating in the one-night-only event.
