You fuckers really need to stop putting Zeppelin in the same sentence with some of those shit bands. Guns and Roses and Aerosmith is fucking hair metal. AC/DC is JUST BARELY better than that.
And indie/alt bands don't claim to be "real rock." If you're giving them shit for that, you just look ignorant as hell...
i dunno, its hard for me to put aerosmith in the glam/hair metal category. they definitely influenced it but they didnt really popularize it like def leppard etc. as for guns n roses, they definitely had their hair metal side but i would probably group them under a more aggressive sub genre, but people don't give them enough credit for some of their less popular stuff.
that being said led zeppelin came before any of these bands and were an immense influence on them. just like you grouped aerosmith and guns with hair metal, people will group led with aerosmith and guns. but led > hair metal any day.
i honestly cannot listen to "rock" from today, shit just isnt what it used to be.
