"The Voice" USA 2015 (Season 9) is entering the most important phase of the competition — the finals. Only four artistes remain in the show after five contestants were shown the doors in the semi-finals last week.

The four finalists — Jordan Smith, Emily Ann Roberts, Jeffery Austin and Barrett Baber — will perform live one last time this season for public votes. They are expected to take up two songs each, and the one with the highest votes will be crowned "The Voice" on Sunday.

Jordan Smith, the lone artiste from Team Adam, rendered wonderfully "Somebody to Love" by Queen in the semi-final. He has been going strong ever since entering the show with Sia's "Chandelier". He is perhaps the favourite for this year's title.

Emily Ann Roberts of Team Blake put up a beautiful show last week, singing "9 to 5" by Dolly Parton. She performed "I Hope You Dance" by Lee Ann Womack during the blind audition and there has been no stopping her since.

Jeffery Austin of Team Gwen survived an elimination scare in the semi-finals when he was placed in the bottom three along with Zach Seabaugh and Madi Davis. He performed "Believe" by Cher during the live shows and then "Make It Rain" by Ed Sheeran for survival last week. He performed "Lay Me Down" by Sam Smith during the blind audition and has come a long away since.

Barrett Baber of Team Blake entered the finals with his performance of "Ghost" by Ella Henderson in the semi-finals. The high school music teacher from Fayetteville, Arizona, made heads turn with his rendition of Jeff Healy Band's "Angel Eyes" in the blind audition and has been going strong since then.

The finalists will perform live again tonight with the hope of winning this season's title.

"The Voice" USA 2015 (Season 9) finals episode will be telecast live at 8 pm EST, Monday, on NBC. The episode can also be live streamed on the channel's official website, though it is restricted to certain areas and needs subscription. NBC also broadcasts the "The Voice" episode free online a day after it is aired on television.
