The battle rounds, in which each coach pairs two contestants to perform together as a team, begin tonight on season ten of The Voice

To heighten the excitement surrounding the episode, the Voice coaches performed Stevie Wonder’s “I Wish." It’s certainly a collaboration of superstar proportions: Blake SheltonChristina Aguilera, and Adam Levine all sing while Pharrell mans the drums.

As always, each team has a celebrity mentor. Previous coach Gwen Stefani will be advising her beau Blake’s team, with Tori Kelly helping out Adam’s, Sean “Diddy” Combs assisting Pharrell’s contenders, and Patti LaBelle as Christina’s team guru. A few weeks earlier, Miley Cyrus shared an Instagram post suggesting that she’ll be key advisor for all teams.
