Listen to Kurt Cobain's Unearthed 'Montage of Heck' Mixtape

A mixtape Kurt Cobain created in 1988 has been given some new life online, offering fans another glimpse into the Nirvana frontman's psyche with a strange but enjoyable collection of music and sounds. 

Courtney Love on Kurt Cobain 'Doping' Note: 'Obviously I Wrote It'

The tape was made on a 4-track cassette recorder grabbing cuts from Cobain's own record collection, the radio, band demos and sounds he made or recorded himself. As United Mutations reports, there were two versions of this tape created -- one short mono version that's about 8-minutes long, and a longer stereo version that runs about 36 minutes (below). And though the recording has existed online for some time, thanks to recent attention from Dangerous Minds it has been getting newfound attention. 

Cobain's assemblage here is genre-spanning, to say the least. From Iron Maiden to The Partridge Family, Sammy Davis, Jr., Frank Zappa and Queen, he runs the gamut. Listen here:
