Butch Vig, best known as the producer of Nirvana‘s Nevermind album and drummer of the band Garbage, recently discussed that he reunited ex-Nirvana members Dave Grohl and Krist Novoselic for a track on an upcoming Foo Fighters album. The track is titled “I Should Have Known,” and will be featured on the next album from Grohl’s band.

The new song sees Novoselic contribute both bass guitar and accordion (!!) to the track. Recording for the as-of-yet untitled album was completed at the beginning of this year, and is being held for a release during April.

Grohl and Novoselic first worked together in the band Nirvana, led by frontman Kurt Cobain. Their breakthrough album was Nevermind, released in 1991, and produced by Butch Vig. The release of the album would usher in a new attitude, sound, and feel for the hard rock/metal and punk community that would eventually be labeled as the “Grunge” genre by the media. During their career, Nirvana released songs such as “About a Girl,” “Smells like Teen Spirit,” and “All Apologies.”
