Butch Vig was the producer behind Nevermind, the game changing album for Nirvana and the 90’s rock scene. And now it looks like Dave Grohl and Krist Novoselic are once in the studio again with Vig.

In the early hours of April 12, the producer (and Garbage drummer) tweeted the following:

“The last 24 hours have been surreal! Had a great gig at the El Rey last night, and spent today recording with Dave, Krist and special guest!”

Though the special guest could be anyone (well, maybe not anyone), the recording most likely has something to do with Grohl’s Sound City Studios documentary. And that’s become an even safer bet to make thanks to the Foo Fighter’s Facebook post, which in addition to saying “hmm…” also includes a tag to Sound City Movie’s Facebook page and a link to Loudwire’s report. Grohl has also reportedly recorded songs with Corey Taylor, Cheap Trick’s Rick Nielsen, members of Ratt, REO Speedwagon’s Kevin Cronin and probably a handful of other for the documentary.

However, it hasn’t been that long since Grohl, Vig and Novoselic were in the studio together. Novoselic performed bass and accordion on the song “I Should Have Known,” which appeared on the Foo Fighters last album Wasting Light (produced by Vig). The bassist has even joined the Foo Fighters onstage numerous times. In case you haven’t seen the Foo Fighter’s documentary Back And Forth yet, you can watch the scene where Novoselic joins the group in the studio after the jump.
