The Sex Pistols may have only been together for two years in the late '70s, but they changed the face of popular music. Through their raw, nihilistic singles and violent performances, the band revolutionized the idea of what rock & roll could be. In England, the group was considered dangerous to the very fabric of society and was banned across the country; in America, they didn't have the same impact, but countless bands in both countries were inspired by the sheer sonic force of their music, while countless others were inspired by their independent, do-it-yourself ethics. Even if they didn't release any singles by themselves, there was an implicit independence in the way they played their music and handled their career. The band gave birth to the massive independent music underground in England and America that would soon include bands that didn't have a direct musical connection to the Sex Pistols' initial three-minute blasts of rage, but couldn't have existed without those singles.
