I'm talking about bands that have breakdowns like as i lay dying, evergreen terrace, bless the fall, misery signals.. you know.. atleast like those good kinda sounding breakdowns.

I really want to know where this metalcore, hardcore, post-hardcore genre all started from..

Ive heard poison the well the well all ready but I want to know what other bands started that stuff with the heavy breakdowns that i can throwdown to.

if you want an example of what kinda music I'm talking about listen to

the year summer ended in june - misery signals

my mirror no longer reflects - poison the well

stuff like that. help me please thanks
