Post-punk [SEP] Introduction
Post-punk (originally called new musick) is a broad genre of rock music which emerged in the late 1970s as artists departed from the raw simplicity and traditionalism of punk rock, instead adopting a variety of avant-garde sensibilities and non-rock influences. Inspired by punk's energy and DIY ethic but determined to break from rock cliches, artists experimented with styles like funk, electronic music, jazz, and dance music; the production techniques of dub and disco; and ideas from art and politics, including critical theory, modernist art, cinema and literature. These communities produced independent record labels, visual art, multimedia performances and fanzines. The early post-punk vanguard was represented by groups including Siouxsie and the Banshees, Wire, Public Image Ltd, the Pop Group, Cabaret Voltaire, Magazine, Pere Ubu, Joy Division, Talking Heads, Devo, Gang of Four, the Slits, the Cure, and the Fall.
