A new album from late Nirvana frontman Kurt Cobain is coming this summer, according to Montage of Heck director Brett Morgen. Morgen, who was given unprecedented access to Cobain’s archives while making the documentary, has said he found over 200 hours of never heard before material and rare music in the singer’s collection.

“We’re going to be putting out an amazing album this summer that I think will answer that question,” Brett Morgen told Bedford + Bowery when asked if he found any new material in Cobain’s archives.

According to Morgen the album “will feel like you’re kind of hanging out with Kurt Cobain on a hot summer day in Olympia, Washington as he fiddles about.” “It’s going to really surprise people,” the filmmaker continued, adding the album will let fans “hear him do things you never expected to come out of him.”

Morgen said he found “107 cassettes featuring over 200 hours of never-before-heard or rarely heard music” in Cobain’s collection while he was researching the doc.

Although the album doesn't have an exact release yet, Morgen’s promise of ‘this summer’ sounds reassuringly soon for fans of the Nirvana frontman.
