Recording of the new Foo Fighters album is nearing the halfway point and the record is sounding different, according to producer Butch Vig.
Vig, who is also the drummer in the band Garbage, said that the Foo Fighters are experimenting with a variety of recording techniques.
Speaking to Kerrang!, he said: "We've been recording at some different locations, but we're almost halfway done with the recording and it's going well.
"It sounds different - we've thrown a few things into the mix, in the recording process, that are going to give the record a different sound and a different feel. It's been a challenge, but it's also been exciting."
The as-yet-untitled LP is the follow-up to 2011's Wasting Light.
