Season 16 Battle Rounds kicked off last night (March 25) on “The Voice” and two mega-talented contenders from Team John Legend crushed a duet of “When We Were Young” by Adele.

Maelyn Jarmon and Savannah Brister tackled the song with vocal grace, beauty, and strength as they fought to win Legend’s vote to advance in the competition.

Covering Adele and doing the song justice is a daunting task for a singer of any skill level. “When We Were Young,” particularly, packs so much emotional depth. The two aspiring singers conveyed the wistful nostalgia at the core of the song brilliantly.

Overall, their stunning duet earned a four-coach standing ovation with John Legend, Kelly Clarkson, Adam Levine, and Blake Shelton jumping to their feet to join the audience in thunderous applause. The video of their performance has been in the Top 10 trending videos on YouTube since it posted.

Levine commended both saying, “You did a great job with a monster of a song” and Clarkson, who has covered Adele during her own live shows on the tour told Maelyn “Your control of your instrument is unreal.” However, she pegged Savannah as her favorite in the round saying, “There’s something that’s so raw about you. You’re 17. I’m going to give this one to you. You are incredible.”

Legend was tasked with a tough choice and he ultimately chose Maelyn as the winner. A preview clip revealed Hannah is the first artist chosen for the Comeback Stage by guest artist Bebe Rexha.

Guest mentors joined the coaches for the first time in this installment with John Legend welcoming Khalid, Charlie Puth, joining Adam Levine, Brooks & Dunn helping Blake Shelton and Kelly Clarkson’s tour partner Kelsea Ballerini teaming with her to help advise the contenders.

All the guest artists were happy to have the chance to work with this season’s crop of talented contenders. As the new kid on the block, Legend is hoping to end Clarkson’s two-time consecutive winning streak.

Last year, Clarkson’s team member Chevel Shepherd took home the title and the “Piece By Piece” singer-songwriter scored a win with her other Meaning of Life tour opener Brynn Cartelli in her first season as a “Voice” coach.
