Chronicling The Avett Brothers and their rise from North Carolina to the top of the charts ("Ain't No Man" reached No. 1 on Adult Alternative Songs back in June 2016), the new documentary May It Last: A Portrait of The Avett Brothers takes fans inside the band's public and private day-to-day life -- and now you can watch a sneak peek.

In addition to reflecting on the decade-and-a-half career of the band, the film also focuses on their present-day collaboration with producer Rick Rubin on their multi-Grammy-nominated album True Sadness.

The documentary, created by Judd Apatow and Michael Bonfiglio over the course of more than two years, will be in theaters for one night only on Sept. 12. Watch the trailer for the film below:
