Jonathan Howsmon Davis (born January 18, 1971), also known as JD, JDevil, or J Devil, is an American singer, songwriter and musician. Davis is best known as the lead vocalist and frontman of the nu metal band Korn, who are considered as the pioneering act of the nu metal genre. Davis' own distinctive personality and Korn's music influenced a generation of musicians and performers who have come after them.
Davis co-founded Korn in Los Angeles, California, in 1993 with the dissolution of two bands, Sexart and L.A.P.D. He had led Sexart during his years as an assistant coroner. Davis rapidly gained notoriety for his intense and powerful live performances with Korn. Anchored by his personal, passionate lyrics and unusual tenor vocals, Davis launched a successful career which has spanned almost three decades, although his popularity declined in the middle of the 2000s. Davis' vocals, which alternate from an angry tone to a high-pitched voice, switching from sounding atmospheric to aggressively screaming, have been the trademark of Korn throughout the band's career.
