In case you were living under a rock or underneath the bridge, Nirvana’s seminal album Nevermind turned 25 on Saturday, an event that was marked by everything from a cover night at Sunnyvale to a recreation of the album cover featuring its now 25-year-old baby. There’s not much left to say about the album that led pretty much every suburban kid to buy a guitar and smash his entire Columbia House cassette collection with it, but there’s plenty left to be said about Smart Studios, the Madison, Wisconsin facilities where an early version of the record was recorded. Luckily, a new documentary is coming along to fix that. The Smart Studios Story, directed by Wendy Schneider, will screen at St. Vitus on Nov. 13.
