I've only heard a couple of Disturbed tracks but they didn't really sound like my kinda thing.
Some of you guys seem to be into technical stuff like Dream Theater, etc. Well, if you can stand a bit (well.. a lot) of screaming and brutality, check out Necrophagist. They're a very brutal death metal band from Germany. But their songs are quite possibly more technical than even Dream Theater. Some of the guitar work is insane.
