Listen to a Previously Unheard Kurt Cobain Song

The track was discovered in Cobain's storage in 2013

With the Montage of Heck release date inching closer, Rolling Stone‘s latest issue bears Kurt Cobain’s face and features an interview with his daughter, Frances Bean.

The website also reveals an exclusive clip of the movie, where the Nirvana frontman is seen jamming out to an original, self-written track. The doc’s director, Brett Morgen, told Rolling Stone that it was a previously unheard song, discovered in Cobain’s storage facility in 2013 (almost 10 years after Cobain’s death).

Montage of Heck premieres on HBO on May 4, but will be playing at the TIFF Bell Lightbox on April 24 and 25.
