The A-side features the album version of "The Past Is A Grotesque Animal" from 2007's Hissing Fauna, Are You the Destroyer?. The song was honored at #168 on Pitchfork's Top 500 Tracks of the decade.

The B-side is a new version of "The Past Is A Grotesque Animal" that was made for the Spike Jonze short film "I'm Here," in which a fake robot band called The Lost Trees perform the song. The song was re-envisioned by of Montreal chief musician Kevin Barnes, the Yeah Yeah Yeahs' guitarist Nick Zinner, and members of the Moonrats.

180-gram light blue 12" vinyl was limited edition of 500 and is now out of print. Hand silk-screened cover by Gemini Tactics.
