Post-punk keeps coming back every twenty years, and every time it sounds nothing like the version before it.

The first lineage is roughly five years long and concentrated in three cities. Manchester produced Joy Division, whose Unknown Pleasures (1979) and Closer (1980) supplied the genre's foundational atmosphere. Peter Hook played bass as a lead instrument. Stephen Morris's drums were treated by producer Martin Hannett as raw material to be cut up and reassembled. And Ian Curtis sang, in a low, sunken baritone, lyrics that could not have existed in any earlier kind of rock. Leeds gave the scene Gang of Four, whose Entertainment! (1979) translated the same anti-rock impulse into something tighter, funkier, and pointedly Marxist: the guitar parts on Damaged Goods and Anthrax — first cut for the band's debut EP and re-recorded for the album — are almost percussion.

New York's contribution was looser. Talking Heads were already three albums in by 1979, and their move toward African polyrhythm — layering several rhythms at once — on Remain in Light (1980) is post-punk in spirit even when nobody used the word. Add Public Image Ltd (the band John Lydon formed after the Sex Pistols broke up), Wire, the Slits, Pere Ubu, and the earlier Television (who'd split in 1978), and the list of bands working under the post-punk umbrella between 1978 and 1982 runs to a dozen or more. What unified them was not a sound but a shared refusal: not rock, not punk, not new wave, definitely not stadium-friendly. Most had broken up by the end of 1983. By 1984 the survivors had mostly moved on to other bands or quit music altogether — Joy Division, in fact, had already become New Order back in 1980.

The second wave arrived a little over two decades on, and arrived with the first wave firmly in mind. Interpol's Turn on the Bright Lights (2002) was reviewed almost everywhere as if it were a lost Joy Division album; the band, in interviews, alternated between accepting the comparison and finding it tiresome. The Strokes' Is This It (2001) wasn't strictly post-punk, but it opened the commercial doorway: a New York guitar band could be a serious press story again. Within a few years, the Rapture, LCD Soundsystem, Yeah Yeah Yeahs, and a dozen more had been pulled into the same critical lineage — LCD Soundsystem, especially, dragging post-punk back onto the dance floor.

In the UK the revival went heavier on Gang of Four. Franz Ferdinand cited the band as an influence around their 2003 debut; Bloc Party's Silent Alarm (2005) brought the jagged, interlocking guitar style to a much larger audience. Editors, who debuted the same year, were frequently described as Joy Division with cleaner production. The 2002-2007 cohort was much more commercially successful than the original: Bloc Party went platinum in the UK, while Interpol's US album would only be certified gold in 2011, nine years after release. It was also, almost without exception, more polished, more produced, and less politically charged than its sources. The records sold, and the fight the originals had picked — was rock politically compromised or not — quietly stopped being a fight at all.

The Brixton Windmill, a small South London venue, was the shared hub where the third wave came together between roughly 2017 and 2020. Black Midi, Black Country, New Road, Squid, Goat Girl, Shame, and Dry Cleaning shared rehearsal rooms, sat in on each other's gigs, and gave press interviews citing Captain Beefheart, Slint, Talk Talk, and contemporary classical composers as often as any first-wave post-punk band. The records reflect the eclecticism. Black Country, New Road's For the First Time (2021) contains saxophone passages that sound transcribed from a klezmer wedding — the Eastern-European Jewish dance tradition. Dry Cleaning's New Long Leg (2021) has Florence Shaw speaking, not singing, over jangling clean-tone guitars. Squid's Bright Green Field (2021) detours into rhythms that are closer to math rock — angular, odd-metered — than to any 1979 reference.

What this cohort kept from the post-punk inheritance is the structural ambition — long songs, time signature changes, refusal of the verse-chorus default — and the suspicion of arena-rock professionalism. What they discarded was the genre's old textural signature. There is no Joy Division impression here. The guitars are clean. The vocals are spoken. The label "post-punk" survives by being so capacious that any guitar band that fancies itself clever and has an aversion to a straightforward chorus can fit under it.

If you played a teenager in 2024 the original 1979 records, the 2002 revival records, and the 2021 South London records back to back without telling them which was which, the three would not obviously belong to the same genre. The guitar tones are different. The drums are treated differently. The vocal idiom is different. What they share is a posture: a guitar band acting as though it is too smart, or too self-conscious, or too politically uneasy to deliver a straight rock chorus — and reaching for whatever that year's studio offers to dodge it.

That posture, not any specific sonic feature, is what "post-punk" actually labels. Every twenty years a new generation of English-speaking guitar bands finds itself in roughly that posture, picks up the term, and applies it to whatever they're already doing. The next revival is probably already two years into rehearsal in a city that hasn't been written about yet. It will sound nothing like Joy Division. It will be called post-punk anyway.
