My tastes have changed quite a bit over the years to the point where I call it a preference in music that I hold... but I'm down for black metal and hardcore punk here and there, the mosh pit has always been a positive experience for me. I'm not a head anymore though, I've actually noticed that I'm not a head in any particular musical genre anymore... not sure if that's a good thing. Music doesn't seem as important as it used to be.
I like BLS and Atreyu, and I'm not sure which direction you like to go in as far as your heavy stuff- but I've had a lot of fun recently at shows for The Apes, Pushmonkey, Airbourne, and Beautiful Creatures... some oldschool faithfuls have always been Fear Factory, TOOL, Bad Religion, Slipknot, Sparta (or "At the Drive In" for the same sound), and Chevelle...
I remember when 16th/32nd note bass drum lines weren't a requirement for every single damned song on the album, when can we get back to that?
