One of the more interesting, diverse and controversial albums of the new century was released on September 4, 2001 — System Of A Down’s Toxicity.

Up is down; left is right. The album features folk, nu metal, banjos and sitars and at first appears all over the place. But it really is a snapshot microcosm of what’s going on in the world in 2001. As each year goes by the album actually becomes more important and that’s rare. It’s a masterpiece that’s never finished.
