Today is an important day in Foo Fighters / Nirvana history! On January 3rd, 1992, Dave Grohl recorded a few of his own songs at the Laundry Room Studio. A couple of these eventually went onto the first Foo Fighters album, and some were even going to be used in Nirvana!
You can read the whole story thanks to @LiveNirvana and hear a few of them with the "Songs From The Laundry Room" EP. Who knows, maybe Dave will release the rest of them at some point!
