James Woolley was the touring keyboardist for Nine Inch Nails during the later Pretty Hate Machine tours (most notably Lollapalooza 1991), and toured with them through most of the Self Destruct tour, including their Woodstock performance, before being replaced by Charlie Clouser in December 1994.
Previous to NIN, Woolley was a major collaborator along with former NIN drummer Chris Vrenna to Chicago band Die Warzau. In 1994, just before NIN hit the road, Woolley contributed heavily to Sister Machine Gun's album Torture Technique.
Subsequent to NIN Woolley made contributions to Die Warzau albums again, particularly 2005's Convenience album. In 1998 Woolley toured with Rob Halford's one-time band Two, which also included John 5 of Marilyn Manson fame. With Two Woolley played live keyboards, and did quite a bit of vocals as well. After Two Woolley did some studio audio work in L.A. By 2005 Woolley had relocated to Chicago. Since 2006, he has been involved in a new band V.O.I.D., who's long awaited album is due in early 2009. The band is led by Woolley and features players Jon Roberts, Mark Pearlman, and DJ Aaron Chase. A demo is available at V.O.I.D.'s MySpace page: [1]. James has also collaborated in the past in a minimal sense to the music of jazz group NRG Ensemble.
