It has been almost a quarter century since Nirvana helped spearhead the grunge movement, and now their third and final studio album 'In Utero' is getting the reissue treatment. Originally released in 1993, the 20th anniversary edition hits stores Sept. 24.

There will be different configurations released, with more than 70 remastered, remixed, rare, unreleased and live recordings available. You'll be able to choose from a standard digital/CD remaster of the original album or a 3-CD/1-DVD Super Deluxe Edition.

The bonus material consists of never-before-heard demos, B-sides, compilation tracks and live material featuring the final touring lineup of Kurt Cobain, Dave Grohl, Krist Novoselic and Pat Smear. That includes the long-awaited release of the complete 'Live and Loud' show from Seattle's Pier 48 on Dec. 13, 1993.

Additionally, a standalone single-disc DVD of the complete 'Live and Loud' show along with several never-before-released bonus performances will also be available on Sept. 24.

Since its release in 1993, 'In Utero' has sold more than 12 million copies worldwide. It spawned the chart-topping singles 'All Apologies' and 'Heart-Shaped Box' and climbed to No. 1 on the Billboard 200 chart.

The surviving members of Nirvana recently joined Sir Paul McCartney onstage in Seattle. They jammed on five songs during McCartney's encore at Safeco Field on July 19. The songs they played were ‘Cut Me Some Slack’ (the song they recorded together for Grohl’s ‘Sound City’ documentary), ‘Get Back,’ ‘Helter Skelter,’‘The End’ and ‘Long Tall Sally.’
