Unlike the “Voice” Battles, where two teammates duet, contestants choose their own songs to sing solo during the Knockouts. The season 27 coaches — John Legend, Adam Levine, Kelsea Ballerini and Michael Bublé — have some hard decisions to make during this phase of the competition.

A new episode of “The Voice” will air on Monday, March 31 and will feature the first round of knockouts.

On this week's new episode of "The Voice," the Knockouts portion of the singing competition kicks off; tune in to see which contestant from each group advances to the next round of the competition.
