@mikelavigne “basically”…nonsense.
You named three uber-popular bands of the ‘70s (as if they constituted the totality of consequential popular music of that decade), besmirched an entire decade’s worth of great music (‘80s), and then capped it all off with the most grossly oversimplified and clichéd summation of popular music imaginable: “Nevermind came along and ‘saved popular music.’”
