In an interview with Fuse.tv, former Hole guitarist and co-founder Eric Erlandson claimed that Kurt Cobain was working on new material around the time of his death. Comparing the solo work to the Beatles' classic White Album, Erlandson spoke about the direction of the rumored demos.
"That's really what he was going towards, a solo album but working with different people," said Erlandson. "I got to see him play it in front of me."
Erlandson also mentioned a cover among the demos, admitting, "I won't say what it is. I don't own the stuff. I just hope that one day it will be released for fans."
Although rare Nirvana demos have been released before, like 2004's box set With the Lights Out, the existence of a possible Cobain solo album is unconfirmed outside Erlandson's claim. Erlandson recently released the book Letters to Kurt, and he reunited with the original Hole lineup for a reunion show last week.
