Kurt Cobain: Montage of Heck director Brett Morgen has now seen his documentary hit theaters and make its cable TV debut on HBO, but he recently teased that an album of music from Cobain would follow this summer. In a new interview, Morgen elaborated on how the new album came to be with public radio station KCRW and The Business radio show.

Host Kim Masters spoke with Morgen in an interview that goes live on Friday (May 8), but Billboard transcribed parts of the discussion for an early preview. As has been stated, Morgen was given access to Cobain's archives to put together the film and through his research, he uncovered a number of Cobain recordings that had never been released. In fact he went through 200 hours of recordings compiled on 108 cassette tapes.

"I went into the archives -- this could be too strong a word -- I liberated a lot of material for the film," says the director. "The primary motivation at that moment was for Frances [Bean Cobain]. I finished the film and there was all this other music. No one asked me to do anything. I just started cutting the thing together and telling the estate they should put this out. Initially, I thought it would be a nice compliment to the film … I don't have any financial stake in the album."

According to Morgen, in addition to the Cobain solo recordings, the disc will also feature some spoken word segments. The director adds, "It feels like you're in Kurt's house, watching him create. You're eavesdropping on him … in the most positive sense of the word, with a great deal of sensitivity, too."

Look for Morgen's full interview with Masters on KCRW's The Business this Friday, and look for the Cobain album to arrive sometime this summer.
