I would especially recommend Pain of Salvation, Spiral Architect, Devin Townsend, Spastic Ink(these guys are crazy) & Maudlin of the Well. Actually, F*ck it and listen to them all

Anyways, just a few more suggestions-

Fates Warning - A Pleasant Shade of Grey
Choosing between this and Parallels is so damn annoying. Epic and awesome.

Psychotic Waltz - A Social Grace
Weird, obscure, complex stuff. The vocals add even more to the weirdness. Definitely something i don't come across very often.
