The Voice‘s final four will be revealed tonight based on America’s votes and the coaches’ scores, but not before the season 1 finalist return as musical guests.

Season 1 winner Javier Colon returns to The Voice stage to promote his album Come Through for You with a performance of “A Drop in the Ocean.” Runner up Dia Frampton will perform with Kid Cudi. Vicci Martinez takes the stage with Cee Lo Green, while Cyndi Lauper joins Beverly McClellan for a rendition of “Money Changes Everything.”

Only one artist will remain for each team after tonight’s elimination – Jermaine or Erin, Tony or Katrina, Lindsey or Chris, and Juliet or Jamar.

Tune in at 9 p.m. ET on NBC. Which four artists will continue on to the final round?
