The audio contained on the 12” pressing of Halloween released on Sacred Bones is a previous recording of the Trent Reznor & Atticus Ross version of the song, which differs from what was released digitally last year.
A lacquer of the ‘previous version’ was cut and then scrapped, because Trent and Atticus decided that they could improve upon the recording.
They went on to create the ‘definitive’ track that is available everywhere digitally.

A MISTAKE WAS MADE when pressing the currently available 12”, and the ‘previous’ version was erroneously included.
To correct this unforgivable error, we are reprinting the CORRECT version and will provide it to those who already purchased it, free of charge. NIN.com customers do not need to take any additional steps to receive your replacement copy. The replacement offer includes those who purchased from other retailers. Customers may contact the original point of purchase for information on how to obtain your replacement from that store.
