Now that Gym Class Heroes have little left to prove, they don't front-load their third LP with hits; the big single, "Cookie Jar," sits square in the middle of this set of buoyant, rock- and soul-inflected hip-hop, which is as witty and fresh as any of the stuff that caught people's ears in the first place, and endowed with more ambitious production. The guests, which include Cool & Dre, Busta Rhymes, Estelle and, ahem, Daryl Hall, add some appealing luster; the best tunes are "Drnk txt Rmeo," the relaxed gait of "Like Father, Like Son" and the hard, weird groove of "Home."
