Foo Fighters frontman Dave Grohl has said he believes that the band's next studio album will be their “heaviest album yet”.

The group are currently demoing songs for the record, which will be produced by Butch Vig.

Grohl said that unlike their last two albums, which were recorded at Studio 606 in California, their next effort would be tracked at his home.

When asked about potential noise complaints from neighbours, the singer told Rolling Stone: “We’re doing a test on Monday.”

He added: “I think this could be our heaviest album yet.”

Meanwhile, Grohl is also working on a new record with Them Crooked Vultures.

His side-project, in which he plays drums, also features Josh Homme of Queens of the Stone Age and Led Zeppelin's John Paul Jones.

The group are set to perform at London's Royal Albert Hall later this month as part of the Teenage Cancer Trust gig series.
