I'd like to think my tastes in death/core metal have matured over the years. I still like Death (the band), Cannibal Corpse (pre-1995), Carcass, Deicide and the like. But I've listened to many newer death/core bands and to tell you the truth, every song is like the next. So far I've listened to As I Lay Dying, Bleeding Through, Darkest Hour, It Dies Today (out of which I liked very few) and some similar bands I can't recall right now.
It seems these new band rely completely on the guttural voice and just distort the guitar and bass, with the drums playing an endless, monotonous beat. Perhaps older (early 90s) bands were like that (i.e.: Master, Brutal Truth, Nuclear Assault), but you'd think the style would've changed after a few years.
Instead, I'm siding with better-voiced bands like Crossfade, Incubus (S.C.I.E.N.C.E. album), Cold, 12 Stones, Dark New Day; which although have a softer tone, the music sounds more melodic. Am I getting older? Have my tastes matured? Ami I too old for new death metal?
