Dave Grohl has discussed his reluctance in the past to approach playing Nirvana music, even after a couple of decades removed from the height of their success. However, he did state that reuniting with Krist Novoselic and Pat Smear for the 'Sound City Players' shows did present some interesting conversations. Grohl revealed that one recent scenario involved an invite to PJ Harvey to see if she might be interested in joining them on a performance of a Nirvana track.

Grohl told NME, "Every once in a while we talk about it. For the 'Sound City' gig here in London [last month], we were thinking about musicians that we could invite because Stevie Nicks and John Fogerty couldn't make it. Someone came up with the idea of doing a Nirvana song with PJ Harvey."

He added, "Kurt [Cobain] loved her and we love her and we thought, 'Yeah, what would we do?' I said, 'God, what if we were to do 'Milk It' from 'In Utero' with Polly [PJ Harvey] singing?' We all looked at each other like, 'Whoa, that would be amazing,' and then she couldn't do it."

Speaking about performing Nirvana songs again, Grohl stated, "The thing is, it's sacred ground. If we were ever to do something like that it would have be right because you want to pay tribute. There's a reason Foo Fighters don't do Nirvana songs, and it's a good reason."
