Raymond Watts (also known as Nainz, Nainz Watts, and Ray Scaballero) is the founding and sole member of the post-industrial music project PIG, sometimes written as <PIG>.
Watts was an early member and periodic collaborator of KMFDM, and has been a visible part of the industrial music scene since the early 1980s. He has toured with KMFDM, Nine Inch Nails, Schaft, Schwein, and Einstürzende Neubauten.
According to the official website, PIG is currently in the studio recording a new album with Marc Heal. Watts, Dr. Shinto and John Gosling released a four-song EP Titled Mellan Rummen on November 15, 2010 on Amazon.com
On June 8, 2012 Marc Heal revealed a demo version of "the first new PIG track in eight years" entitled "Drugzilla (Rough As A Hog's Arse Mix)" via Cubanate's Official Facebook page and providing their followers a link to his personal SoundCloud page. The link was reposted by Watts a few hours later. A second demo entitled Shake was released on July 15, 2012; again via Heal's Soundcloud page, this time also noting Dan Abela as engineer.
