As the second season of Glee gets closer, the hype machine is fully underway. Fox has just released an all-new promo with bits and pieces of the drama, music and excitement that we can expect from the forthcoming season. We already know about guest appearances from Carol Burnett, Javier Bardem, and Britney Spears (complete with an entire episode dedicated to her music), and there's sure to be plenty more surprises down the road. After the jump check out the short promo which makes use of the Glee cast's rendition of Jay-Z and Alicia Keys hit song Empire State of Mind. Keep in mind though that if you haven't finished the first season, there's some spoilers to be found. The second season premiere of Glee hits Fox on September 21st.
