After a stint with Chicago industrial band Die Warzau, Woolley's tenure with Nine Inch Nails began in 1991 when he replaced Lee Mars for the band's Lollapalooza Tour. The keyboardist remained with Trent Reznor's group through the recording of 1992's Broken EP and 1994's The Downward Spiral, and while Woolley isn't credited on either album, he appeared in the videos for "Wish" and "March of the Pigs."
