Necrophagist is most definitely heavy. Maybe not compared to some of the grind you listen to, but they have their brutal moments. Ive seem em live 5 times, and my jaw was on the floor every time. Coming from guitar player(currently on hiatus to being run over by a drunk-o) they are absolutely amazing. They play alot of stupidly fast thrash riffs, so that may be where your not hearing the heaviness.
To be honest, while we are both huge metal heads obviously who love the brutal shit. Our taste's are slightly different. Im into the technical shit, which you probably have realized. Being a lead player, its what I strive for in my music. Also Im a huge fan of progressive music, which explains my love of such bands as meshuggah and Gojira. And you've heard my song, its totally progressive.
You on the other hand from my perspective are VERY similar to my bands video guy jeremy. I know all about the grind culture, as Im around it almost daily. I know you also appreciate and love other styles of metal, but grind lovers are their own breed IMO. Dont get me wrong, you know I love me some grind. But Grind is ALL about that brutal heaviness, and insane rythems. Which has its place. I also personally am not a huge fan of Grind style vocals. Myself also being a huge thrash fan, enjoy a variety of vocal types in my metal. The only thing I cant stand however, are bands who fucking squeal 90% of the time. Although I do love me some Devourment.
Does that make any sense? Or am I just to stoned?
