(NEW YORK) -- It's been 20 years since Nirvana unleashed its masterpiece Nevermind, and Universal Records will be celebrating the anniversary with a deluxe five-disk edition, according to Spin.
The set, which drops Sept. 19, will contain four CDs of music -- including B-sides, rarities and unreleased material -- as well as a DVD with footage from some of the band's BBC radio appearances and a previously-unreleased full-length concert video.
While fans got a good chunk of rare Nirvana on the 2004 With The Lights Out box set, the new Nevermind deluxe edition goes deeper into the archives. There is some speculation on the BBC radio performances, but Spin guesses that they are "most likely from four in-studio sessions recorded between 1989 and 1991," including segments from John Peel and Mark Goodier's radio shows.
This reissue isn't the only new material fans will get from the band this year. According to a statement, Universal is also planning a number of "various events and releases" celebrating the groundbreaking group.
