It's ok kids, grunge music isn't dead, it's just hanging out on eBay waiting to be discovered. That's the lesson one fan learned after buying a Nirvana session reel off eBay, and discovering seven unreleased recordings, including two never-before-heard tracks from the Seattle band. The session reel dates back to February 15, 1993, when the band were recording what would be their last studio album, In Utero, at Pachyderm Studio in Minnesota.

One of the unreleased tracks, an untitled instrumental featuring Dave Grohl playing all instruments, is a short, sharp 1.52 minutes long, while the other, also an instrumental, 'Lullaby' is thought to include Kurt Cobain on drums, but frankly sounds like the guys messing around in the studio. The other five songs include two versions of 'Dumb' and the Grohl-penned-and-performed track 'Marigold'.

You can listen to the two unreleased tracks below - they're not going to change the world, but hey, they'll probably make a few superfans happy. And in other Nirvana-related news, The New York Times reported there's going to be a touring exhibition of Kurt Cobain's art, works and possessions. Details are scarce, but the project is in conjunction with Cobain's trust manager, daughter Frances Bean Cobain, and deceased musician estate manager Jeff Jampol. Now that's something definitely worth seeing.
