Listen to the first track from Montage of Heck: The Home Recordings.

An album of Kurt Cobain home recordings will be released this summer to coincide with the DVD release of Cobain documentary Montage of Heck. The compilation, culled from 200 hours of recordings from over 100 cassettes, was created by director Brett Morgen.

In an interview with Kim Masters for KCRW’s The Business, Morgen explained the process of creating the album. “I went into the archives — this could be too strong a word — I liberated a lot of material for the film,” he said. “The primary motivation at that moment was for [daughter] 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 complement to the film… I don’t have any financial stake in the album.”

Montage of Heck: The Home Recordings compiles various unheard songs, demos, and “musical experiments” from the late Nirvana frontman. One of the tracks is an early acoustic version of ‘Sappy’, which can be streamed in full below. A full-band studio recording of the song later appeared on the 1993 charity compilation No Alternative with the title ‘Verse Chorus Verse’.

Montage of Heck: The Home Recordings will be released on November 13. [via CoS]
