yea those are good...

it's really hard to describe the sound. Most of the bands I listed don't have to much screamo. Marilyn Manson screams a bit, but not usually through the whole song. Just think...lower pitched music and heave drumming compared to high guitar sounds. That's the best way I can describe it.

ohh...and slipknot is good too. CannabilCorpus has some crazy stuff and you might want to try listening to some death metal.
