Yeah, very reminiscent of Moving to Mars, definitely. I don't think he aced the only live performance of the song at iTunes festival (if you only take into account his voice), but for Atlas I feel he could deliver a great live performance.
Yes; Moving to Mars; Atlas - it's true that Chris' voice truly is spectacular in a lower register. It just has a very emotive timbre to it; you can feel the angst, the threat, and the confusion in his voice. I'm glad he doesn't over-use it, though.
