actually i rarely listen to metal this days, it bores me really, most of it, i cant remember the last time i heard metal record that blew my mind.
i mainly listen to classical, prog rock and jazz fusion this days. i also love dark ambient and experimental electronica but like metal havent listen to that stuff for some time now.
i'm kind of a fase guy, i'll eventually get back to metal, i always do, but i cant help but feel that there isnt much interesting things happening in the metal world, at least imo, when i hear a new band, i always think, i've heard this before....and about technicality and complexity? well most metal is quite simple actually, especially in structure and composition , of course you got your ocasional virtuoso, but thats not enough to keep me interested.
i do think that one shouldnt limit himself to one style of music, and if you're a musician, knowledge is a weapon, if you only listen to metal, you gonna sound like some other metal band, but if you listen to more styles, you can pick up little things, progressions , details, little things that can give your sound some originality, and it helps a lot in composition, believe me.
anyway call me pretentious, but i always want to find new things, better things, different things in music, thats why im always look for new music and i rarely listen to metal.
i guess i'm a bit bias to classical, since imo its the most rich genre, like metal can givel all emotions but on a higher lever imo, complexity, technicality and especially the most important thing about music, composition.
anyway, conclusion, open your mind, ive been a metalhead for many years, listen only to metal, but it really helps as a musician to be open minded.
