Sonic Youth is a popular rock band from the 90s. They were a huge part of the noise rock scene and a heavy influence on the indie movement. Sonic Youth is most known for their songs "Teenage Riot" and "Superstar". They have been praised for redefining what rock guitar could do and used unordinary tunings in a lot of their songs. Though they all seemed pretty punk, most of the band members are open about being huge Dead Heads.
