I guess that punk became mainstream because:
1-the controversy of looks, behaviour and fashion trends and teh media coverage it gained.
2-the fact that it wasn’t really “new” or outside of the “already seen before” so people were already acquainted with that.
As SussMusik points out: most of the groups were recycling and having a fresh new look at previous styles as a reaction to a world (both music and fashion) that went all over the top in the late 60’s early 70s. So it was a way back to Exp-Jazz, Mods, TeddyBoys, early Rock’nRoll etc
Check out Bo Diddley comments on touring with (opening for) the Clash…He could dig’em alright cuase he considered there was nothing unusual about them, he saw that before. Only the volume they played got him going “WWWOOAAAHHHH”
Look at the Beatles Hamburg-Era photos, and compare with The Clash early pics, Everything looks familiar, from music to attitude and,er… personal hygiene
Glitch&Noise will never be mainstream that way cause it’s echoing styles that have never been mainstream.
John Cage, Stockhausen, Pierre Henry, etc, people never have been used to that.
