Think you've got the ultimate release of Nevemind because you scored a vinyl copy? Think again. Arriving slightly after the album's 20th anniversary, the Nevermind Super Dulexe Edition($136). It includes the remastered classic in its entirety, studio and live B-sides, the first-ever full release of the pre-Nevermind demos recorded at Butch Vig's Smart Studios, boombox recordings of rehearsals, and the Devonshire mixes of the album that became one of the best albums of the '90s, as well as a 90-page book and a DVD of a 1991 Paramount show. North America gets only 10,000 copies, while the rest of the world has to fight over the remaining 30,000.
