His nickname comes from a scene in Blue Velvet. With a wide variety of face paint designs, Jeffrey's most known look is that of a butcher. However, he revealed a new look in the music video of "Your Soul Is Mine", showing a tan skin mask that somewhat resembles the infamous "Leatherface" from the Texas Chainsaw Massacre movies. His most recent incarnation is that of a mask resembling human hands. He is signed as a solo artist to Suburban Noize Records.
Jeff Hatrix is the co-founder, and lead vocalist of the Cleveland Industrial Metal band, Mushroomhead. He was also the singer of Cleveland-based thrash metal band called Hatrix, as well as fronting the band Purgatory in the mid 80s.

When asked about the upcoming record, Jeffrey Nothing stated: "The whole album is about escaping reality. People choose a variety of ways to feel better in the face of the depression that can be caused by trying to survive in a world that can seem completely uncaring and smothering,” commented Nothing about the album. “‘The New Psychodalia’ is like a new safe hallucinogenic that makes all the ugliness in the world beautiful, with no harmful side effects. The entire album is kind of like a twisted, thought provoking view of the truths. It exposes the lies of the American dream that has really become more of a nightmare.” 
On August 22, 2011, Jeffrey Nothing debuted the first single from The New Psychodalia on RevolverMag.com
