On its sixth studio set, the Philadelphia-based quartet—drummer ?uestlove, MC Black Thought, keyboardist Kamal and bassist Leonard Hubbard—returns to hip-hop basics. An homage to Big Daddy Kane and Kool G. Rap, "Boom" finds Black Thought deftly imitating both MCs. He also takes center stage on lead single "Don't Say Nuthin." The minimalist track, produced by Scott Storch, and its eye-grabbing video, is garnering much attention for the group. Other highlights include the melodic "Star" and "I Don't Care" (featuring Dom). Among the disc's hidden gems is "Din Da Da," which uses George Kranz's early-'80s club smash, "Trommeltanz (Din Daa Daa)," as a base for ?uestlove to stretch out on the skins. The result is stunning. "The Tipping Point," named after Malcolm Gladwell's book of the same name, proves that you can go home again.—RH
