There certainly were “tribes” back then, you could tell what bands people were into by their clothes or hair styles, early to late 80s easily identified.
As far as I can see Brit Pop was the last “movement” of any real substance that penetrated regular life - if a rock star having champagne at No 10 is regular life that is. But what I mean by that is that unlike many current rock or metal stars etc that are known within their genre but are totally anonymous outside of it, Liam & Noel Gallagher were of a genre but known to the general public who weren’t into their music.
Nowadays people may know the current stars but to me it seems there is a lack of genre, it’s just music. Time for a guitar based revolution methinks.
