The year 2014 has been pretty monumental in celebrating the life of the late and great Kurt Cobain.

April 5th marked 20-years since his tragic passing that revisited heartache and spurred an endless sea of tributes to the iconic ’90s grunge star. In addition to this, Nirvana took over headlines again in April when they were inducted into the Rock And Roll Hall of Fame for 2014, which saw four rockin’ females stand-in for Cobain performances at the awards. And now as Consequence Of Sound ( via Dangerous Minds) has just revealed, a mixtape created by Cobain back in 1988 has been unearthed, propelling the sorely missed artist straight back to the spotlight.

The mixtape entitled Montage of Heck is a creepy 36-minute production from the young mind of Cobain, which was pieced together a full year before Nirvana’s debut release Bleach.

The cut’n’copy mix features snippets from radio shows, distressing sounds of human suffering, toilets flushing, his favourite Daniel Johnston obsessively ranting about the devil, bone-chilling distortions as well as a whole mix of extremely disparate music from Cobain’s long, eclectic mix of adored artists including The Beatles, Simon & Garfunkel, Butthole Surfers, Queen, The Velvet Underground and so much more.

Cobain created the mix on a four-track cassette recorder and upon the initial listen, it honestly feels like one is thrust into the disturbing depths of hell, Kurt you’re fearless whacked-out Willy Wonker-esq pilot, you, the terrified, unprepared passenger who has no idea of their fate.

Despite such an insane adventure through sonics that aren’t what one would deem as “comfortable”, listeners really gain a further appreciation of Cobain’s aptitude for sound and mixing.

Take a listen to Dr. Frankenstein Cobain’s taped experiment below but be warned, this mind-bending head-fuck is not for the light hearted, but boy, it is damn fun.
