System of a Down goes in too many directions at once for me. I can't wrap my head around their music on a typical day, but there is one exception. "Chop Suey," from their 2001 Toxicity album is one that I don't turn off when I hear it. It's a near-perfect blend of chaos and order that is brought together by pounding drums and grinding guitars. It was also released right before the September 11, 2001 attacks, and reminds me of what was going in in the world at that time every time I hear it.
