According to The Pulse Of Radio, an old friend of late NIRVANA frontman Kurt Cobain named John Purkey, who runs a YouTube account called The Observer, recently uploaded four videos containing cassette audio of NIRVANA demos from the late eighties. Purkey claims that the tapes were given to him by Cobain himself. They include early recordings of songs that would eventually make up the band's debut LP "Bleach", as well as material recorded with MELVINS drummer Dale Crover and audio of early, pre-Dave Grohl "Nevermind" recordings featuring Chad Channing on drums. Purkey has also offered comments on each tape.
The tapes amount to about two hours of material, some of which has been heard by fans before, with much of it sounding raw and unpolished.
Grohl, who joined NIRVANA in 1990, told The Pulse Of Radio a while back that the band recorded a lot of material that has never seen the light of day. "There's a lot of unreleased stuff that no one's ever heard," he said. "There's a lot of unreleased stuff that I've never heard. I mean, I was the fifth drummer. I didn't join until 1990, but spent a lot of time demoing and recording basement practices, and things like that."
A 2015 documentary called "Kurt Cobain: Montage Of Heck" used rare home video footage, interviews, artwork and music from the late NIRVANA leader's own personal archives to tell his life story.
A number of personal items once belonging to Cobain went up for auction last year, including his Blockbuster video rental card, some original Cobain sketches, NIRVANA's MTV Video Music Awards trophy for the "Smells Like Teen Spirit" video, and some of the proofs for the "In Utero" album artwork.
