Foo Fighters frontman Dave Grohl has reflected on the musical impact of Kurt Cobain, as well as delving deep into the emotional toll of Nirvana's unfortunate split.

Appearing on Apple Music’s Medicine At Midnight Radio, Grohl also considered how the band were hugely taken aback by their rise to worldwide fame in the early '90s.

“We were still in our van and we were just watching this happen in front of us,” he said.

​“The shows were getting bigger,” he continues. ​“The crowds were getting bigger. The crowds outside of the shows were bigger than the crowds inside the shows. We could see that something was happening, but we never expected that it would turn out to be as big as it was. I don’t think any of us expected that.”

Contemplating the band’s split after Kurt Cobain tragically died by suicide in 1994, Grohl said their untimely break-up was one of his “life’s greatest heartbreaks”.

“Of course, it was an incredibly challenging experience and ultimately one of the greatest heartbreaks of my life that Nirvana isn’t still here today making music,” he said.

“Whether it would be called Nirvana or something else. It is one of my life’s greatest heartbreaks that Kurt isn’t still here to write more amazing songs because it’s pretty clear that he was blessed with a gift. I think it’s safe to say that he was the greatest songwriter of our generation. I’m very proud to say that I got to be his drummer and play those songs every night.”

Grohl and Pat Smear revealed on Howard Stern's radio show recently that they join forces with Krist Novoselic from time to time to perform Nirvana songs.

Smear was a touring guitarist with the grunge icons, and stated that the last time the three of them got together was at the house where the Foo Fighters recorded their new album - Medicine at Midnight.

“Every once in a while, me and Krist and Dave get together and we do play as if we’re Nirvana,” Smear said.

“So I don’t have to miss it — we do it. If we’re in the same town together, or whatever, we’ll get together and jam.”
