The Voice stage is lit for high drama once again. And with good reason: after tonight, just three singers from the original field of 64 will remain in the competition. At the stage, Carson Daly greets us and then recounts some of last night's musical pyrotechnics when Trevin Hunte, Cassadee Pope, Terry McDermott and Nicholas David all sang for their survival. Tonight, we'll learn how well their performances were received as America's votes are revealed.
