The limited, numbered Super Deluxe Edition more than lives up to its name as one of the most expansive and ambitious collections of its kind with only 10,000 copies available in North America, and another 30,000 for the rest of the world. The Super Deluxe features not only the original remastered album and accompanying studio and live B-sides, but the first full official release of the pre-Nevermind demos recorded at producer Butch Vig's Smart Studios, as well as boombox recordings of subsequent rehearsals through which the listener can actually experience "Smells Like Teen Spirit," "Come As You Are," "On A Plain" and others that take shape before his or her very ears. The Super Deluxe also offers an altogether new perspective on the finished Nevermind album exclusive to this format in the form of the Devonshire Mixes: the album as produced and mixed by Vig as opposed to the commercially released final version produced by Vig and mixed by Andy Wallace. Rounding out the Super Deluxe are a pair of previously unreleased BBC recordings and the aforementioned 1991 Paramount show available for the first time and exclusive to this format on CD and DVD (which also features all four music videos from Nevermind), as well as a stunning 90-page bound book full of rarely and never-before-seen photos, documents and various other visual artifacts of the Nevermind era.

If Nevermind's sound is familiar now, it's only because thousands of rock records that followed it were trying very hard to cop its style. It tears out of the speakers like a cannonball, from the punk-turbo-charged riff of "Smells Like Teen Spirit" onward, magnifying and distilling the wounded rage of 15 years of the rock underground into a single impassioned roar. Few albums have occupied the cultural consciousness like this one; of its 12 songs, roughly 10 are now standards. The record's historical weight can make it hard to hear now with fresh ears, but the monumental urgency of Kurt Cobain's screams is still shocking. --Douglas Wolk
