I will chime in with my own twopence here...
I'm not a fan so much of the traditional, straight hardcore...don't much care for the old 80's stuff - I consider Henry Rollins to be one of my literary heroes, but I never cared much for the music - but I do like a lot of music that gets lumped in with hardcore.
I can't possibly gush enough over bands like American Nightmare/Give Up The Ghost, The Hope Conspiracy, or Modern Life Is War. I guess these guys are pretty standard hardcore.
Converge is my favorite band hands down, but I don't really consider them hardcore; I actually just call them punk rock, which gets me in trouble with a lot of punk purists, but I figure a band that for 15 years has done their own thing their own way, and is still going on as hard and as arasive as ever is punk rock to me. Most of what I like is more hardcore influenced, rather than being purely hardcore - Orchid, Pg. 99, City Of Caterpillar, just about every band that has put out music on Level Plane records...most of what is released on Deathwish also greatly appeals to me.
I guess to me, the term "hardcore" in music is interchangeable with "punk rock" and I don't use either one in their strictly traditional sense; they both describe music that I find to be deeply passionate and played with a great deal of heart. A lot of what falls into the hardcore genre just feels too cut-and-paste, riff-by-numbers, and scene obsessed. There's a great deal of insincerety from what I have witnessed, so I try to distance myself from the label itself, and just listen to what moves me.
I'm just doing what I can to prove all the people who told me that "when you grow up, you'll grow out of this yelling screaming noisy music" wrong...
Edit: Tommy, I don't know why this is, but it just seems a little strange to me that you used to listen to Converge...cool and all, but hard to picture.
