Sonic Youth changed the landscape of guitar music through their experimentation with free-form noise, off-kilter rock/pop songs and dissonant alternative guitar tunings. The core members of the band (Kim Gordon, Thurston Moore and Lee Ranaldo) formed in 1981. On episode 35 of Philosophy of the World we revisit the output of this essential indie rock band from their early years to the end of the 1980's. We start with their debut EP highlighting Sonic Youth's no-wave roots, journey through EVOL and Sister which established them as powerful underground artists and finish off the show with instant classic Daydream Nation launching them into the pantheon of legend.
