"[Kurt] was headed in a direction that was really cool. It would have been his 'White Album,'" Erlandson told the music-driven TV network Fuse, referring to the Beatles' classic record.
"That's really what he was going towards, a solo album but working with different people. I was really excited about some of the stuff he was working on. I got to see him play it in front of me. That's why I was really sad [when he died]. I was like: 'Oh, man, not only are you cutting off a life, but a message to the world, a musical path.' … He was cut short. Who knows where the music would have gone."
Cobain, the front man for the influential grunge group Nirvana, shot himself after years of battling drug addiction and depression. He was 27.
Erlandson is a guitarist, who played with Courtney Love, Cobain's wife, in the band Hole.
