Trent Reznor has posted a rare seventy-five minute documentary covering their 1994-1996 "Self Destruct" tour online. You can check it out below. The video was previously avilable only on the "Closer" VHS that was released in 1997. The video includes concert footage as well as behind-the-scenes stuff as well.
