These early rounds of The Voice are the most entertaining, and the best – and NBC clearly is aware of this, because this week it’s squeezing three consecutive nights out of The Voice, starting tonight. That’s six hours, fully two-thirds of NBC’s schedule between now and Wednesday, and no one gets more screen time, or a career bump, than the judges. For this tenth cycle, the judges returning from last time are Adam Levine, Blake Shelton and Pharrell Williams, and replacing Gwen Stefani for Cycle 10 is Christina Aguilera.
