Nirvana's classic (and final) album, In Utero, turns 20 this Sept., and, as with Nervermind two years ago, it will receive a deluxe reissue to mark the occasion.

The Steve Albini-recorded album marked a huge sonic departure from the group's breakthrough, Nevermind, and spawned hits like “Heart-Shaped Box” and “All Apologies.” Tragically, frontman Kurt Cobain took his own life less than eight months after the album's release.

A rare (and potentially NSFW) television teaser from In Utero's 1993 release has been posted online, to build anticipation for the reissue. It features the band taking a pregnancy class from comedian Bob “Bobcat” Goldthwait, all in drag, before ultimately “giving birth.”

Watch the teaser below.

Pre-order information and further details about In Utero's reissue are expected to arrive soon.
