Reznor asked Sean Beavan to mix the demos of Pretty Hate Machine, which had received multiple offers for record deals. He mixed sound during Nine Inch Nails' live concerts for several years, eventually becoming an unofficial member of the live band and singing live backup vocals from his place at the mixing console. Flood's production would appear on each major Nine Inch Nails release until 1994, and Sherwood has made remixes for the band as recently as 2000.

Reznor began smashing his equipment while on stage; Rockbeat interviewer Mike Gitter attributed the live band's early success in front of rock oriented audiences to this aggressive attitude. Nine Inch Nails then embarked on a world tour that continued through the
