If punk taught us that anyone can do it, post-punk showed you could do anything with it. By the late ‘70s, the anarchic idea of punk was disseminating far beyond rock music and becoming manifest in the discordant disco of Gang of Four, the roughed-up reggae of The Slits, and the primitive electronic experimentation of Throbbing Gristle. But post-punk expanded punk’s emotional vocabulary as well, through the brooding romanticism of goth demigods like Joy Division and The Cure. And future superstars like U2 and R.E.M. were also products of this moment, forging a link between post-punk’s wiry intensity and anthemic ’80s alt-rock.
