Post-punk was more revolutionary than punk itself

Reynolds's central provocation is that punk, despite its explosive cultural impact and shocking imagery, was in musical terms fundamentally conservative — essentially a stripped-down revival of 1950s rock 'n' roll and 1960s garage rock dressed up in aggressive new clothing and rhetoric. By mid-1977, he argues, punk had already collapsed into self-parody and predictable formula, its "Year Zero" rhetoric of total rupture undercut by how musically familiar most punk actually sounded.

Post-punk, by contrast, took punk's initial energy and genuine break with the mainstream music industry and pushed it somewhere entirely new, incorporating dub reggae's spacious basslines, American funk's rhythmic complexity, German experimental rock's textural adventurousness, and eventually early electronic and disco production techniques. Reynolds treats this as the real revolution punk had merely promised but never delivered, arguing that post-punk's more diffuse, harder-to-market sound is precisely why it has been historically underrated compared to punk's simpler, more iconic imagery.

Takeaway: punk broke the rules everyone already knew about — post-punk invented rules nobody had thought to break yet.
