The Foo Fighters frontman has admitted his former Nirvana bandmate's suicide in 1994 shook him so much he found it difficult to listen to songs which provoked any kind of emotion..
Speaking to Anderson Cooper on CBS' '60 Minutes' on Sunday night (26.10.14), he said: "Losing Kurt was earth-shattering, and I was afraid of music after he died.
"If I heard a song that even touched on an emotion in me, I would turn it off.
"I was so terrified because to me, that's what music always was. It was a direct connection to my heart."
Earlier this year, Dave reconciled with Courtney Love, Kurt's widow, after putting their feud behind them at the Rock and Roll Hall of Fame ceremony in April.
He explained: "It was the Hall of Fame ceremony, but it meant so much to all of us personally that sometimes you forgot about the other stuff - like the arena and the trophy - and focused on real, personal things.
"I saw Courtney walking past [earlier in the night], and I just tapped her on the shoulder and we looked at each other in the eyes and that was it - we're just family.
"We've had a rocky road. We've had a bumpy past, but at the end of the day we're a big family and when we hugged each other it was a real hug."
