American punk vs British punkWatch
Unless you’re including 2000s pop punk lol
In my opinion The Dead Kennedys are more of a hardcore band then punk (in terms of musical genre). Hardcore was hugely influenced by the British Punk scene.
McLaren seized the opportunity of the climate at the time and the Pistols were born... Yep, that's as punk as it sounds.
Blondie had longevity because they adapted with the newer trends (not very punk) and became part of the new wave scene which granted them more fame then any of their punk exploits would've.
