Listen to Nine Inch Nails on iHeartRadio

Nine Inch Nails are getting fans prepped for their upcoming tour with a look back at one of their old treks. 

Trent Reznor and company have posted a rare documentary about their "Self Destruct" tour, which ran from 1994 to 1996, on their Tumblr page.  Reznor warns that the doc does contain some "Not Safe For Work" material.  But he also notes that it has plenty of concert and behind-the-scenes footage, as well as cameos from David Bowie and Marilyn Manson.

Nine Inch Nails have also posted other rarities to the website, including an acoustic performance of the "Downward Spiral" track "The Becoming."  The band is scheduled to hit the road in its new form later this year.
