Roots of Billy Corgan

Kevin Patrick Shields is an Irish musician who achieved international fame as the lead vocalist, guitarist, and primary songwriter of the alternative rock band My Bloody Valentine. Their studio albums Isn't Anything (1988) and Loveless (1991) established Shields as a pioneering figure in the shoegaze genre. His textured 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.

Van Halen was an American rock band formed in Pasadena, California, in 1972. Credited with restoring hard rock to the forefront of the music scene, Van Halen was known for their energetic live performances and the virtuosity of their guitarist, Eddie Van Halen.
