The album that blew the music world apart in 1991 is getting the "deluxe edition" treatment for it's 20th birthday. Universal announced the re-release of Nirvana's 'Nevermind' will hit stores in September and boasts all kind of extra goodies for grunge enthusiasts like myself.

In September of 1991 an album, from a virtually unknown band from Seattle named Nirvana, entered the Billboard charts at #144. By January of '92 it had replaced Michael Jackson's 'Dangerous' at #1 and was selling 300,000 copies a week. On the strength of singles like 'Smells Like Teen Spirit' and 'Come as you Are',  Nirvana's 'Nevermind' ushered in a whole new era of rock music that served as the long overdue nail in the coffin of "hair metal". The landmark album has sold more than 30 million copies to date.

To celebrate the 20th anniversary (and make a few extra bucks), Universal announced that a Super Deluxe Edition of the album will be released in North America on September 20th. The 5 disc package will include the original album remastered, previously unreleased tracks, BBC radio appearances, rarities, b-sides, rare live recordings, alternative mixes, and an unreleased concert in its entirety on DVD.

The press release also states that the "20th anniversary of Nirvana will be marked throughout the year, with various events and releases."

I'm not sure how much more unreleased material there could be after the release of their box set; 2004's 'With the Lights Out'. Although it is unspecified what unreleased recordings will be included, we can all hope for an unheard gem from the vaults of Nirvana. Will we get one? Probably not, but here is the last 'new' song released by the band.
