It was a busy night for Adam Levine on tonight's edition of 'The Voice.' The singer performed a new song with his band, Maroon 5, and had to say farewell to two of his team members. On top of that, he had to watch his two remaining contestants compete against each other.

The show started off with the eliminations from last week's performances, and it was announced that Javier Colon made it through thanks to the American vote. Levine was then forced to choose one more contestant to save from his three remaining team members -- Jeff Jenkins, Devon Barley and Casey Weston.

Levine told Jenkins, "The first time I heard you sing, you blew my mind," while telling Barley that he was the "most-improved" contestant on the show. But, in a surprise, he chose Weston, saying he originally thought he was going to pick Jenkins but had a last-minute change of heart.

Of Levine's two remaining contestants, Weston was up first. Her song was the ballad 'I Will Always Love You' popularized by both Dolly Parton and Whitney Houston. Levine stressed to Weston that she make the song her own and not try to copy the superstars' versions. His advice paid off, as her restrained rendition of the song played well to the all of the coaches.

Prior to Colon's performance, Levine took the stage with his band Maroon 5 to perform their new single, 'Moves Like Jagger,' a homage to legendary Rolling Stones singer Mick Jagger. The group was joined onstage by Levine's fellow 'Voice' coach Christina Aguilera, who also appears on the studio version of the track.

Then it was time for Colon to perform. The crooner, who has been a favorite on the show since the beginning, took on Coldplay's 'Fix You.' Like he's done all season long, Colon did a stellar job performing the song, prompting Levine to tell him that he has one of the best voices he's ever heard.

Levine will have to say goodbye to Weston or Colon on Wednesday night, with one of them making it into the finals next week.
