Ready for your close-up?

When Oxygen's The Glee Project premieres Sunday, 12 aspiring singers and actors will get a shot at a seven-episode arc on Fox's series -- but not without a price.

For the duration of the series, the contestants will compete in a series of challenges to test their skills in front of the camera and in the recording studio, just like Lea Michele, Cory Monteith and Co., do as part of the song-and-dance smash.

On Sunday's premiere, Glee's breakout star Darren Criss, who appears as Blaine Anderson, mentors the cast as they perform a group number of Stevie Wonder's "Signed, Sealed, Delivered."

Check out the exclusive clip above for more from Criss and the Glee Project cast ahead of the show's premiere Sunday at 9 p.m. (EST) on Oxygen.
