Punk rock is a subgenre of rock and roll with roots in garage rock, but it's generally faster and more aggressive than garage. Punk was a rebellion against the hippie culture's idealism and appearance. The flower children’s righteous idea of making the world a better place was met with the stark reality of the punks' world in disarray. New York, the birthplace of punk, was almost bankrupt in the early 70's and when the Sex Pistols appeared in England, unemployment was severe with well over a million people out of work. Crime and drugs were rampant in NYC; parks were littered with used syringes. England incurred inflation, oil shortages and strikes. So bell bottoms were out, replaced by tight pants and those beautiful long locks were gone, replaced by hair cut short, and even cut off as skinhead culture emerged.
