brutal/technical/ and sometimes melodic

How about The Black Dahlia Murder? Pretty heavy, pretty melodic. Not bad.
Demigod by Behemoth...I dunno if you'd call them melodies or what...
 
anata, The faceless, intestine baalism, lykathea aflame, decapitated, illogicist, odious mortem, theory in practice all seconded...
I know you must know about them but I haven't seen it mentioned... so... Nile!
