BoO: The melodies, riffs and the general atmosphere in the music
Whitechapel: Really differing vocalist, the riffs are something that can help you single them out...also the vocal structures.
Suicide Silence: The vocals, the chugchug-tremolopicking-chug pattern and just the general sound of it. Easy to point out. Drums, frequent use of Euro-blasts and fast pumpbeats.
Daath: Speedy riffs and chord use. The chord progression and vocals give it away pretty easy too. Drums. Drums.
I'll sum it up. Every band has it's own riffs...It's hard to put your finger right to it but it's usually the riffs. Really, I think i've justified myself.
Really, It's not hard. Someone remember the first time they heard some thrash or death metal? Didn't it sound the same back then?
Those were deathcore bands. Not my favorite bands.
Favorite band:
Misery Signals:
Unique guitar layers.
Polished sound.
Ambient and these kinda dreamy melodies.
Progressive yet catchy and easy to get into.
Jazz-y drums at some parts.
Just has not happened before in that genre or style of music.
EDIT: I TOTALLY WANKED THE EDIT BUTTON ON THIS ONE. FUCK YOU, VIKK
