Metal drummers normally hit hard on their kit and all that punch is often gone with compression and limiting.
(especially when clipping is induced on snare to chop off all it's peak)
Not sure you understand why we use compression on drums.. its to give the drums MORE punch. And unfortunately, most metal drummers DON'T normally hit hard, and need to have their drums replaced. Yes, a lot of punch is lost during mastering to get these volume levels, but that's not really something you can avoid by 'not compressing' during the mix - in fact, it'll end up much much worse.
Distorted guitar can have sometimes up to 5 dbs of dynamics hidden in their bass content, wich if removed with Eq, will only leave an annoying standing noise in the overall mix.
Personally I'm not a fan of subwoofers flubbing out every time a guitarist does a palm mute, and are you seriously saying that anything above 100hz in a guitar is just annoying noise? Why do you listen to metal?
Vocals are probably what is going to determine the amount of dynamics in a song and compressing them by 25 db may make them seem big as hell, but they mostly become too present and incoherent.
Don't get me wrong, metal is all about taming dynamics and working on that low end so it delivers the energy a mix deserves.
But, compressing everything till every ounce of dynamic is gone and the spectrum barely moves so you can then pan everything the same way you do it for all mixes, is to me, a bit lazy and should require more innovation.
Vocals pretty much NEED to be crushed, otherwise they'll sometimes be buried, sometimes be riding on top. I'll agree it could be more interesting with some extra vocals, etc. (Ermz always does a fantastic job with this, for a good example), but again that's a songwriting/producing thing and not a mix thing.
After all this I'd feel bad about derailing the thread if I didn't comment on Ryan's mix, so I'll do that in a sec.
It sounds quite nice, also a few things..
- kick way too loud, as others have said, and its very thuddy, too much lowmids I think.
- I'd go for more bottom mic on the snare if possible? Just a bit more crack, its quite tubby/top-micey
- bass could be a bit more present? Guitars could come up a touch too?
Your cymbals sound a bit cheap here, but as always, HUGE. Is it the mics you're using or what? OHs are always really hard for me to nail.
