Christina Aguilera was a ball of energy backstage Tuesday (June 7) when "The Voice" wrapped its first live show, as the singer shared her thoughts on her team's performance with a crammed line of journalists.

"Tonight I saw enormous growth," Aguilera told Billboard.com. "My favorite moments have been in spending quality time with my team. To see every one of them have that desire and hunger, to get in the position to be the best -- I loved that they took in every note that I gave them...it was so exciting to me to see them be fighters."

Aguilera's team took on Blake Shelton's, the first stage of a round where 16 contestants will be whittled down down to eight by opening the voting to viewers. The top vote-getter on each team will stay, as will one additional singer chosen by the coaches. Cee Lo Green and Adam Levine's teams will face off on next week's two-hour show.

However, all four superstar judges took the "Voice" stage to perform a medley of Queen hits, including "Bohemian Rhapsody," "We Will Rock You" and "We Are the Champions." Watch below.

What audiences at home saw was a string of performances that were widely lauded by the coaches, and only one that was dinged. Here's an assessment of how each artist came off from inside the sweat-inducingly warm soundstage.

TEAM CHRISTINA

1) Raquel Castro
Song: Ke$ha, "Blow"

Judgment: A highly choreographed presentation that was rich in attitude drew accolades from all four coaches. As a perky teenager, she should get a boatload of votes from teens who identify with her and make it to the next round.

2) Beverly McClellan
Song: Melissa Etheridge, "I'm the Only One"

Judgment: Beverly's powerful vocal chops earned her props from the coaches with Levine reacting to the smack Aguilera was delivering by saying, "You're so good I shit myself." But performing the song exactly like Etheridge would put it more in line for a karaoke championship than the semi-finals of a TV competition.

3) Lily Elise
Song: Fergie, "Big Girls Don't Cry"

Judgment: The coaches tried to be polite by assigning blame to an army of dancers. There was no denying it: A truly mediocre performance that started off very rough. She's a goner.

4) Frenchie Davis
Song: David Guetta feat. Kelly Rowland, "When Love Takes Over"

Judgment: Frenchie was an early favorite when she was on "American Idol" and she is a force to be reckoned with here. Levine told her, "You made me love that song," while Green praised her seasoned stage presence and Shelton marveled at her combination of power and control. She has "the voice," but will the public vote strictly for vocal ability?
