As far as the -core genres go, I recommend Shogun. Very mathy stuff with a heavier dose of metal, moreso than most -core bands

Shogun - Nation of Masochists
Gluttons for punishment,
all of you
flogged to the beat
of two thousand years of misery
torn by the wild tooth of contempt
thrown to lions
insatiable appetite for the flesh of man
heal yourself,
heal the holes in your hands
self negated by the hand of hope, eye of
death stared down selflessly
divine sadness cast down from above,
masochists glorify divinity
partake of your blood filled cup, consume for
salvation from pettiness
cast no light upon me
sleep your whole life, spread the sadness
worship madness
wake up, pound on your coffin
let your savior hear you,
let your savior find you,
let your savior save you,
let your savior fuck you
*double edit*
These lyrics in particular crack me the hell up.
Cacozielical Irony
your words leave me speechless
chop your language into pieces
slather saliva on your dictionless syllables
with the ignorant dull knife of your tongue
emulate prefabricated nuances,
designed like the rest of pop culture to
create comfort in repetition,
repetition, familiarity and the cliché
animate your hands to add dimension
but gesture not towards me or speak
your mindlessness though broken teeth
disarm your forging, splicing comma
hang at the end of this modifying rope
sacrifice your own voice your whole life
speak like you learned your own language
articulate like you were born with a tongue
dont just bounce between
the walls of your ears
worship the gods of grammar
worship, bow down
you dont have a voice of your own
*triple edit*
just found these lyrics and they keep getting better and better
Three A.M. Nice Tie
Deliver me from evil,
deliver me for one thousand dollars
my act of faith is the
perfect evolution of idol worship
press my hand against the TV,
be my cathode ray savior
my act of faith covers
the high price of playing god
if only your broadcast ministry
were prime time,
all the riches of a spiritual world
in need could be yours
instead, this farce of healing appeals
only to those most desperately famished
of greed and humor
one day our paths will cross and with my
fists of morality you will find that it
is you who is mistaken
about a great many things
is that gibberish the tongue of god?
or are you choking on your own blood?
die for my sins and burn in hell
