Nine Inch Nails has released a documentary that followed the group while they were on the Self Destruct tour from 1994 to 1996. It shows a behind-the-scenes look at life on the road, and we even get a chance to see David Bowie and Marilyn Manson when they make appearances. Trent Reznor recently stated that Nine Inch Nails would be heavily touring in 2013 and 2014, and that the band has reinvented itself. Meanwhile, his side band How to Destroy Angels with wife Mariqueen Maandig released their debut album on March 5th.
