Birthed in the playful amateur experimentalism of New York's 1970s no wave scene, Sonic Youth are potentially the definitive American rock band of the post-punk era. From the creative blossoming of EVOL, to their mammoth art rock masterpiece of "Day Dream Nation" to the surprising commercial victory of "Goo", the band continuously bucked convention, and remained in flux creatively up until their unofficial ceasing in 2011.
