Pigface is an industrial rock supergroup formed in 1990 by Martin Atkins and Bill Rieflin. Both had drummed with Ministry, and were pleased with the notion of a rock music band with two drummers, rather than the usual one. The duo formed Pigface, and began a revolving-door collaboration with many experimentally-minded musicians, many of whom — especially early on — had recorded for the influential industrial music record label Wax Trax. Trent Reznor was also an early partner, when, due to legal troubles, Nine Inch Nails were prevented from recording under that name. "Suck" — cowritten with and sung by Reznor — was something of an underground hit, and Reznor later rerecorded the song. Rieflin eventually left Pigface, leaving Atkins in charge. The dozens--perhaps hundreds--of musical collaborators to record and perform with Pigface have ensured that each album, and each song, is unique. This practice has, however, led to some negative criticism due to a perceived lack of continuity. Pigface concerts are characterized by high-energy performances. Frequently there will be upwards of 10 people on stage at any time during the show. Not only that but Martin Atkins and the rest of the band love interacting with the audience, and members of the audience are nearly always invited on stage for the encore.
