Nine Inch Nails are set to close out the first day of Chicago's annual Riot Fest, tomorrow, September 15th. Ahead of their impending headlining set, Trent Reznor, Atticus Ross and Co. are holding a fan Q&A at Reckless Records, the beloved Chi-Town record shop. The best part? You don't have to actually be there to witness the conversation — NIN are streaming the whole thing right now on Facebook. Between Reznor and Ross' recent ADD VIOLENCE EP and "Twin Peaks" appearance, there should be plenty of interesting topics up for discussion. Tune in below.
