When Ludacris described his seventh studio album as “theatrical,” he wasn’t kidding—listen to the triumphant, dramatic beat of “Undisputed,” which the Atlanta-born rapper peppers with his trademark sticky mic skills. A Floyd Mayweather cameo adds to the pageantry, and the rest of the set benefits from a star-studded cast: T-Pain lends a soulful hook to the dreamy “One More Drink,” while “I Do It for Hip Hop” unites onetime bitter rivals Nas and JAŸ-Z on a loving ode to the culture.
