Brian Phillip Welch (born June 19, 1970), better known as Head, is an American musician best known as one of the guitarists and co-founder of the nu metal band Korn and his solo project Love and Death. Along with fellow Korn guitarist James "Munky" Shaffer, Welch helped develop Korn's distinctive sound, a mix of sirenlike shards of dissonant guitar that mimicked a turntablist's various effects and rumbling down-tuned riffing, that defined the nu metal aesthetic beginning in the mid-'90s.

After becoming a born again Christian, Welch left the band in 2005 to focus on life as a father and to pursue his own solo career. He released his debut Christian album Save Me from Myself, in 2008. He reunited with Korn on-stage at the Carolina Rebellion on May 5, 2012 for the first time in seven years, and on May 2, 2013, officially announced rejoining the band. Welch and Munky were ranked at No. 26 of Guitar World's 100 Greatest Heavy Metal Guitarists of All Time.
