Nevermind turns 20 on September 24. To celebrate, the band’s label, Universal, is reissuing the album as a four-CD set featuring unreleased recordings. The set will also include one DVD featuring BBC radio appearances and unreleased concerts, and the CDs will feature B-sides and rarities. The deluxe package hits stores on September 19 in the UK and September 20 in the US. Nevermind was the Seattle band’s breakthrough album and first album to feature drummer Dave Grohl, who later formed the Foo Fighters.
