According to the ancient Greek philosopher Aristotle, “Teaching is the Highest Form of Understanding.” While it’s hard to say whether Xzibit‘s aim on new single H.F.O.U. was to edify or simply to get a few things off his chest, there’s no question that the man’s dropping knowledge – and those who listen closely enough just might learn something. Backed by an sample of the Beach Boys’ Good Vibrations (co-produced by Xzibit and The Futuristics), the Cali mainstay hits the mic with righteous fury, starting off by describing his first night spent homeless in California and building to a full-on indictment of our society’s callousness toward those in need: “The frequency of tragedy, it happened so rapidly that we became numb, we embrace this insanity.” On the back, Detroit mainstay Trick Trick jumps on board to gruffly tackle the conflict between his Christian faith and the cruelty surrounding him. After hearing him drop a single this aggressive and thought-provoking, can there be any doubt that X to the Z is back in full effect? You tell me – and, if you’re craving more keep it locked for release details on new album MMX.
