The song was released in a limited edition of 13 copies, on flash drives encased in real human skulls, for Halloween 2011. Each skull cost $5,000. A website was also set up, streaming the song on an endless loop.
On April 19, 2014 the band released a condensed 50 minute version, separated into 10 tracks, on a translucent vinyl LP for Record Store Day, limited to 7,500 copies. It was released on CD and Digital on May 19, 2014.
