Details are still scarce about the Season 3 premiere of 'Glee,' but we can present you with these new teaser images.

The new shots feature Rachel in the chorus room and Mercedes leading the charge on a very purple stage. The episode is called 'The Purple Piano Project,' (Tues., Sept. 20, 8PM on Fox) hence the purple outfits.

Several TV spots have featured the cast singing 'We Got the Beat,' but no word on whether that will make it into the premiere episode.

Check out the preview pictures below.
