What happens when hip-hop's two kings -- and best buds -- par up for their first full CD a deux? Royal genius! The disc by Jay-Z and Kayne West (a.k.a the Throne) teems with their famed bravado (on the jubilant "Otis") and deep introspections, like when they dispense advice to their future sons on the riveting "New Day." (Def Jam/Roc Nation)
