Big Black - Songs About Fucking
Swans - pretty much anything, but let's say "Children of God"; high volume absolutely required
Foetus - Flow (again, one of many possible selections)
Your more death-metal-y stuff I actually kind of like, but it doesn't do anything for me when I'm angry.
I could totally listen to In Flames as something to drift off to nap time.
I suppose when I'm actually angry, I end up listening to certain kinds of things that are soothing in a dense way. Like, um, The Arcade Fire, maybe. Uplifting, but not saccharine. Or like Rocket From the Crypt, which is speedy and with an aggressive edge (I'm thinking of "The State of Art is on Fire" here), but not actually angry. Anger sours after a while, and it's nice to sort of transmute that.
