"This ain't hookah. You hit this shit a few times, you might see the future," Ab-Soul says of DMT in "Pineal Gland," his dark, mystic ode to the drug. The same thing can be said of the MC's rhymes; moments like this one induce chills as Ab-Soul seems to crack the corners of the universe by venturing deep into himself. Rarely have psychedelia and hip-hop been crossed so well. His style can be abrasive at times — though in the best way possible — but Ab is a sensitive soul, as he shows in the long-overdue "Double Standards," which is about gender roles and sexuality. Control System was one of the very best albums of last year, and though its release was overshadowed by friend and label-mate Kendrick Lamar's Good Kid, M.A.A.D City, don't make the mistake of missing the train on this Top Dawg.
