Check out the song Red Rock at their Myspace page. Although I discovered them through Paynie's documentary on Youtube), mostly I think the embeddable live performances I could find aren't a good reflection of what's good about them in the studio.
Caveat: their chief influence is clearly Tool's Aenema-style and Perfect Circle (duh). But since I like Tool, and they're good at it, that's fine. They also throw in a healthy dose of epic Euro-metal key changes a la Iron Maiden and In Flames. Importantly, they do a good job pulling off those Maynard-eseque powerful, open vocal crescendoes.
