I always like to sing barefoot, but when I first started doing these dates with the symphonies, I of course thought I should clean up my act, being a Jewish girl from Long Island with a little bit of a trucker mouth. So I wore a gown and some high heels.

There's always been an element of 'right time, right place' to Nine Inch Nails. When we stepped onstage at Woodstock '94, I could sense it. I get goosebumps thinking about it now. Like, 'I don't know how we did this, but somehow we've touched a nerve.'

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.
