(NBC) - Three singers are still vying for the title of "The Voice."
NBC's singing competition series wraps up with a two-night finale starting Monday, and the final trio have plenty of work ahead.
After sweating out her spot in "The Voice" finale Christina Grimmie is braced for what's ahead.
"I've been through exhaustion on this show, learning songs last minute, and it's all in a week for live TV. All of that is just going to pay off," she says.
Also preparing for the finale are Coach Blake Shelton and his artist, Texas teen Jake Worthington.
"Absolutely, it's go, go, go time," Worthington says. "I talked with Blake about the songs we're going to do and it's going to be a hell of a week."
For Usher, it's about finding songs that complement the artist's background, in his case 38-year-old Josh Kaufman of Indiana.
"America isn't just voting with their ears, they're voting with their hearts too," Usher says. "This isn't just karaoke, we have to put some thought into their performance."
It'll be multiple performances for Kaufman and the others, meaning the most preparation yet.
"More wardrobe, more vocal lessons, more rehearsals, more of everything," Kaufman says. "So it's going to be a really hard week, but a really fun week."
Each of the finalists will perform two songs on Monday night's show, and each of the
Four coaches will also perform.
The two-hour finale Tuesday night will also feature special performances by Ed Sheeran, One Republic, Coldplay and Tim McGraw.
