Tonight's final performances will determine a winner.
(NBC News) When Cassadee Pope won "The Voice" last fall momentum seemed clearly on her side going into the finale.
This time around, the wrap-up promises more suspense.
"I'm think it's more up in the air this season that it's ever been," says "Voice" coach Adam Levine.
"It comes down to, literally, a performance," Levine says. "Michelle can win, the Swons can win. Danielle can win."
The focus is on the finalists and their performances tonight.
Tomorrow night lots of guest stars are lined up for the show, leading up to the announcement of the winner.
Cher, Christina Aguilera, Bruno Mars, Pitbull, Florida Georgia Line and Nelly are all slated to appear.
