Dave Grohl and Krist Novoselic have refused to rule out playing more Nirvana reunion shows.

At a recent surprise show Cal Jam Festival, Grohl and Novoselic launched into a set of six Nirvana songs as part of Foo Fighters’ encore. The band performed the likes of ‘Smells Like Teen Spirit’, ‘All Apologies’, ‘In Bloom’ and more as John McCauley and Joan Jett stood in for Kurt Cobain alongside former touring guitarist Pat Smear.

Grohl, discussing the shows in a new interview with Kerrang, said “After we played the Rock & Roll Hall of Fame, I considered the idea that, if there was an opportunity, we could do it again.

“But it’s delicate territory,” he added. “You can’t treat it like just another show,” Grohl added. “It’s very complicated, and very special. In those moments, when it just happens naturally, I think is the best way.”

Krist Novoselic added: “Personally, it was great to play with those guys again, and to play those songs.”

It was only yesterday that the duo said that their experience playing old Nirvana songs was a “spiritual” and “emotional” one.
