WATCH: New trailer for Nirvana reissue

September marks two decades since the release of Nirvana's third – and final – studio album and as is often the case with these things, it's getting the full reissue treatment.

You can expect a lush, deluxe package similar to Nevermind's re-release two years ago. Before we get the full details of the new version of In Utero , we have this extremely surreal trailer for it.

It finds Kurt, Krist and Dave, apparently all pregnant and in drag, attending an antenatal class with Bobcat Goldthwait of Police Academy fame.
