THE VOICE
NBC, 8:00 p.m. ET
Today this show begins a new stage – the playoffs, which are noteworthy because they’re live, and thus out of control of the producers and the ever-inventive editors. This is where these musical competition reality shows either achieve liftoff or start flaming back to earth, so it’s worth watching to see how this year’s panel of judges handle the specific demands of live TV. (Over on American Idol, for example, Mariah Carey has yet to learn even the most basic truths about keeping your remarks brief and playing well with others.) Oh, and one other reason to watch this live show tonight? Former judge Cee Lo Green returns – to sing.
