'The Glee Project' sneak peek: Vulnerability is the buzzword

"Glee" fans -- has Oxygen's "The Glee Project" been satisfying your summer withdrawal symptoms? Zap2it snagged an exclusive clip of tonight's all-new episode, in which "Glee's" vocal arranger and songwriter, Nikki Anders, spends some time in the studio with the contestants.

The episode features guest mentor Dot Marie Jones, known as Coach Bieste on "Glee." She has the contestants sing Pink's "Please Don't Leave Me," while exposing their vulnerable side, and later, the gang collaborates on another song that showcases vulnerability -- Gary Jules' "Mad World" -- for the music video of the week.

In the studio, Nikki works to connect with the kids -- Cameron and Melissa in particular. Watch the exclusive clip below and let us know what you think of Nikki's coaching style.
