On "The Voice," airing Monday, April 20 on NBC, the “Knockouts Rounds” conclude. Each artist is paired against a teammate to perform individually, while their direct competitor watches and waits. Multi-platinum and Grammy Award-winning music icon, James Taylor, will serve as the Mega Mentor and be on hand to work with all of the coaches and their artists as they prepare for this challenge. The coaches alone will choose the winner from each Knockout to advance. Each coach will have one steal in the “Knockouts.” In a new twist, the four artists that were saved during the Battle Rounds will compete in a Four-Way Knockout. Carson Daly ("TODAY Show") hosts.

Check out a sneak peek with James meeting the contestants below.
