Jeffrey Nothing, also known as Jeff Hatrix (born Jeffrey Lewis Hetrick May 5, 1963) is an American singer-songwriter and musician. He is best known as the former clean vocalist for American alternative metal and industrial metal band Mushroomhead. His nickname comes from a scene in Blue Velvet. With a wide variety of face paint and mask 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. Two of his masks were made from face-molds of famous actors Christopher Lloyd & Bela Lugosi. His most recent incarnation is that of a mask resembling human hands. He is signed as a solo artist to Suburban Noize Records.
