Remember, back in the 90’s, when grunge broke, and there was this
whole slew of bands leading the charge– Nirvana, Soundgarden,
Mudhoney, etc.? And you liked a lot of them…I mean, they were
good bands. Sure, they were just borrowing from older
influences, like Sabbath or the Stooges or whatever, but that’s just
how rock and roll works; the new sounds are always informed by those
that preceded them.

But then, after that first or second wave of bands, you started to get
that next wave; the “copies of copies,” like Stone Temple Pilots, or
Collective Soul, or Creed. And sure, technically, they met all
the same criteria as those earlier bands, but still, they were just…
a bit hollow. They just lacked… something. Like a xerox of a xerox, the
important details got lost, and you were left with this sort of bland
facsimile of something better.

Take note, Indie Rock is in that same phase right now.
