The 36-track instrumental record, recorded in a ten-week period last year, is available in a variety of download options and as a physical copy.

The options are a free download featuring the collection's first nine tracks, a $5 download featuring the whole album, a $10 two-CD set (either via the website or in shops from April 5) and a $75 deluxe edition, including a hardcover book and a data DVD and a Blu-ray disc featuring high definition recordings and a slide show.

There is also an “ultra deluxe” limited edition version for £300 which features the same items as the $75 version, but also signed and numbered by Trent Reznor.

Full details and the free download are on NIN.com now.
