Voyeurs is the only album by 2wo, a musical collaboration between Judas Priest vocalist Rob Halford and former Red Square Black / future Marilyn Manson / current Rob Zombie guitarist John Lowery also known as John 5. Nine Inch Nails' Trent Reznor receives executive-producer credit, with the actual production duties being handled by Bob Marlette and Skinny Puppy's Dave Ogilvie. Voyeurs is stylistically similar to the Red Square Black - "Square" EP (1994) which was produced and co-written by Marlette and featured Lowery on guitar.
The so-called "pre-Reznor Mixes" of Voyeurs were made available as a free download at Rob Halford's official website in 2002. The download package included "Shout" and "Scream", which remain unreleased. Also included was a demo of "Silent Screams" which was later recorded for Halford's Resurrection. Though the album was unsuccessful in sales, it gained a cult following years later.
