So what do you do when you're bored with Death Metal?

So for the past I believe two years or so I've been on a real death metal kick, but recently I've gotten so tired of it that if I hear one more unoriginal song with drop d tuning and cookie monster vocals I'm liable to punch somebody (and yes this is to an extent me venting my frustration). So that said I'm looking for some music recommendations, preferably something fairly progressive and a little more sophisticated. If it helps I've been really enjoying bands like Russian Circles, Neurosis, and Isis lately. I still really enjoy (later) Death, Atheist, and Cynic too.
