Clip is from new documentary 'The Smart Studios Story'

Foo Fighters frontman Dave Grohl has discussed first joining Nirvana in a clip from an upcoming documentary.

The new film is called The Smart Studios Story and will be released on Record Store Day Black Friday (November 25). It tells the story of Nirvana producer and Garbage drummer Butch Vig’s Wisconsin studio, Smart Studios.

In this clip, Sup Pop Records boss Jonathan Poneman and Grohl discuss how the band came to work with Vig. Grohl says that when he first joined Nirvana, the band were working on material that sounded different to everything before and that he kept hearing about “Butch, Butch, Butch”.

Meanwhile, Grohl could be working on new music, with a fan claiming that he spoke to the star recently about his “new record”.

In March, producer Butch Vig suggested that Grohl was working on new music and that it wouldn’t be under the Foo Fighters name.

A fan – and fellow musician – named Damien Curry recently uploaded a photo with Grohl in which he said that the pair chatted about “our kids, his new record, producing”. See that picture beneath.

A press representative of Grohl declined to comment to NME.

Grohl previously denied any intention of going solo despite his band hinting that they would embark on a hiatus following 2014’s ‘Sonic Highways’.
