Jack Cassidy, nephew of David Cassidy, returned to The Voice on Monday to face off against Hunter Plake in the singing competition's battle rounds, and the talented vocalist threw down with everything he had.
Cassidy and Plake, both members of Team Alicia, went head-to-head with dueling renditions of Robyn's "Dancing On My Own," and it was truly a battle round for the ages.
After the powerful performance, all the coaches had nothing but praise for both performers. Gwen Stefani complimented Cassidy for his rich voice and unique notes, but heaped praise on Plake, telling him that he really needs to record an album.

"Your voice is so beautiful, and you are so emotional when you sing," Stefani praised.
Adam Levine was equally wrapped up in Plake's powerful, emotionally charged voice.
"From the first note you sang, I was completely drawn in," the Maroon 5 frontman explained. "The entire time, I thought to myself, 'Wow, this guy is the real deal, and he's making me feel things."
Blake Shelton said he was equally conflicted, with both contestants delivering very different and wildly impressive performances that showed a wide range of strengths.
"I don’t know what you're going to do," Shelton told Alicia Keys. "I just hope anybody who has a steal feels the same way I do right now."

Finally, it came down to Keys' decision, and it wasn't an easy one.
"Hunter, you are a very internal individual, and it's very intriguing and interesting and I want to peel back the layers of your mind," Keys pondered. "And Jack, you have this thing about you that you're so bright and you have a light that's really, really brilliant around you."
Ultimately, Keys chose Cassidy as the winner of the battle round. However, that didn't mark the end of Plake's time on the show. Levine and Stefani both pressed their buttons to steal the young singer, and Plake ended up jumping on board Team Gwen.

After the battle was over, Cassidy hopped on Twitter to congratulate Plake, with whom he said he's developed a close friendship. The singer said he's "more pumped [Plake] got stolen than taking the win TBH."
Cassidy also shared his appreciation with his coach, tweeting, "A tremendous thank you to @aliciakeys for the faith you have in me to find new levels of freedom in myself so love can speak louder volumes!"
