Kevin Patrick Shields is an American-Irish musician, singer-songwriter, composer, and producer, best known as the vocalist and guitarist of the band My Bloody Valentine. My Bloody Valentine would become extremely influential on the evolution of alternative rock with their two studio albums Isn't Anything and Loveless, pioneering a subgenre known as shoegaze. Shields's texturised guitar sound and his experimentation with his guitars' tremolo systems resulted in the creation of the "glide guitar" technique, which became a recognisable aspect of My Bloody Valentine's sound, along with his meticulous production techniques. Following My Bloody Valentine's dissolution in the late 1990s, Shields became a frequent guest musician, producer, engineer, and remixer with various bands and artists, including Experimental Audio Research, Yo La Tengo, Dinosaur Jr, and Mogwai. In 1998 he became a touring member of Primal Scream.
