The Voice released a Rat Pack inspired video to promote the return of the show tonight (2/26) on NBC with a new judge and some new twists too. The original American Idol, Kelly Clarkson, joins the show as a judge along side Blake Shelton, Adam Levine, and Alicia Keys. Another new addition to the show this season isn't part of the cast, but rather, a new feature on those cool spinning chairs. This season, instead of just having a button to push when a judge wants a contestant on their team, the chairs come equipped with 3 new buttons that block a specific coach from being able to claim a contestant. I'm sure Adam and Blake will be having a field day with those!
