The music video from next week's episode has been released:
The Glee Project Season 2 - Party Rock Anthem Full Music Video - YouTube!
It's notable because of who's missing from it: Taryn. Since the video is shot before the elimination, Taryn either went home voluntarily, was eliminated early OR was edited out of the video for some reason. She seemed pretty much like a fish out of water. I wonder if it was just too much pressure for her.
Also, The Hollywood Reporter has posted pics of the mentors in next three episodes: Samuel Larson is next week ("Dance-ability"), Cory Monteith is episode 3 ("Vulnerability") and Naya Rivera is episode 4 ("Sexuality"). You can see at least the backs of heads to recognize some of the contestants. Based on the picture, as of episode 4, Mario, Alanna, Charlie and maybe Michael and Tyler are still there.
