While there are already a handful of SXSW parties worth attending (and you’ll be getting our list of them later this week), Soundgarden just went and upped the ante. The band have announced via their website that they’ll be performing their fourth album, Superunknown, in its entirety for the first time ever during the festival as part of the first iTunes’ Festival to take place in America. They’ll be playing it in commemoration of the 20th anniversary of the album, which was originally released on March 8, 1994. They’ll be playing the album front to back on March 13th at the Moody Theater. The album will be the subject of a reissue that will be out on June 3rd. Here’s what the posting said:

Soundgarden will be headlining night three of the iTunes Festival at SXSW in celebration of the 20th Anniversary of Superunknown (available on iTunes for pre-order on March 11th). Chris Cornell, Matt Cameron, Kim Thayil and Ben Shepherd will perform the album front to back for the first time ever.

Superunknown was the band’s breakthrough album, containing the hits “Black Hole Sun,” “Spoonman,” “Fell on Black Days” and “The Day I Tried to Live,” among others. And while previous albums Badmotorfinger and Louder Than Love found the band at their most metallic, this was the album that brought them to quintuple platinum status and perennial rock radio airplay. It still holds up years later, despite the ubiquitous nature of the aforementioned songs, and it’ll be pretty exciting to hear it played for the first time ever if you’re a fan of the band. If not, you’re not going to be starved for newer music to find if you’re in Austin.
