Rage Against The Machine, Death Grips

Yes, a known mispress exists where the vinyl record inside the sleeve for The Money Store by Death Grips contains audio from both Evil Empire by Rage Against The Machine and The Money Store.

The record features the first half of the Rage Against The Machine Evil Empire album on side A, and the last half of the Death Grips The Money Store album on side B.

The vinyl itself came housed in the proper packaging for The Money Store, including the correct cover art, printed inner sleeve with lyrics/credits, and a sticker on the shrink wrap that may have indicated the unusual content (though it's primarily identified by the actual audio).

The mispress can be identified by the matrix/runout information on the vinyl itself, which matches the details for both albums' pressings.
