Scorching performance await the madlang people because just like last year, the week-long Ultimate Resbak leg will force the aspiring singers to strategize and challenge each other in the face in order to fill the “seat of power.”

Who among the resbakers will face off with grand finalists Elaine Duran, Ranillo Enriquez, John Mark Saga, John Michael Dela Cerna, Charizze Arnigo, Jonas Oñate, Violeta Bayawa, Julius Cawaling, and Shaina Mae and Rafaello?
