Foo Fighters are allegedly recording their new record in 12 different cities around the world. Dave Grohl and company were spotted earlier this week in Chicago, where they were allegedly working with Steve Albini at Electrical Audio. Meanwhile, Triple M radio has an interview with an unidentified Australian fan who ran into Grohl at bar, where Grohl reportedly told him they were also working with Butch Vig, and that the group was “using a never-previously-used recording technique that’s unique to [Albini’s] analog studio.”

Grohl may have reconnected with Albini last year, right around the reissue of Nirvana’s In Utero album. Albini engineered both that original record and a “2013 mix” for the reissue, for which he also contributed extensive liner notes.
