Isis and Opeth. or try some Trivium. Maybe a little too hardcore but i think you'd get into em.

You don't listen listen to the former and the latter is nothing like the what the OP is asking for. Stop posting. Seriously. All you do is regurgitate what those around you are talking about even if it doesn't make sense in the context of the thread. You don't develop your own opinions and your time on this board is spent seeking approval from some the social hierarchy this place has managed to develop.

As for my recommendations, Spock's Beard (especially the albums V and Feel Euphoria), Frameshift (check out Unweaving The Rainbow), and Aghora (technical/jazzy metal but with female sung vocals, the self-titled is the superior of the two albums imo)

If you like Tool maybe you'll like A Perfect Circle - actually I'm quite curious as to why no one reccomended it before.

I like both equally. The self titled has a more jazzy (as you mentioned) and yet slightly harder to get into sound while I find I can throw in Formless and listen to it just about any time.

As for recommendations, Earshot sound sort of like a cross between Tool and something with more radio friendly structures. Sort of like a watered down Tool. I'd also say Miocene has a bit of a Tool sound although often a bit nu-metal in spots. Either way, they should have a little bit of appeal if you're into that sort of thing.
