"I wanted to thank him in the way that he helped me. And I reluctantly went backstage, feeling weird and ashamed, like, 'Hey, I'm the guy that puked on the rug.' And again, I was met with warmth, and grace, and love," Reznor said.
"And I started to say, 'Hey listen, I've been clean for ...' I don't even think I finished the sentence; I got a big hug.

"I didn't think we were done," he said.Trent Reznor is currently working on new Nine Inch Nails material, that will be released in 2016.
