Well, I can list a few for you off the top of my head which I think you may like.
These bands are pretty much more Alternative than anything else but here goes:
Karnivool, CoG, Epicure, and Dead Letter Circus, all are Australian based bands, all good in my opinion.
Calla is another good choice.
But I would Urge to listen to this band:
"And You Know Will Know Us By The Trail of Dead".
^ actual band name.
