When it comes to the “official” Punk genre, which began in the ‘80s if I’m not mistaken, I don’t really know much about it. Loud, angry, slam dancing in the audience. That’s the extent of what I know.
But it’s about the ‘angry young man’ state of mind and The Who embodied that theme pretty much from the start right through the ‘80s IMO.
Young Man Blues, Bell Boy, Sea and Sand, In A Hand or a Face, Slip Kid, ...
The Sex Pistols formed in 1975 and broke up in early 1978, and are seen as the first of the Punk Rock bands. The Clash formed in 1976 and credit the Sex Pistols.
I very much consider some of The Who’s stuff (earlier than ‘75) Punk Rock. Maybe calling them proto-punk would be accurate.
Agreed. IIRC, their film Quadrophenia was another example of the "angry young man" theme.
