The Knockout Rounds begin tonight, pushing the competition to the next level. There still are steals for the judges to use, if they have the inclination to save a losing contestant – but there are fewer steals in this round, so they’re employed more sparingly. Overall, that means more people going home after each episode, beginning now. And beginning now, the key advisor for all four coaches is someone who knows a little bit about winning one of these musical competitions: Kelly Clarkson, the winner of the first season of Fox’s American Idol.
