The Glee cast sure knows how to get down!

In a new promo spot touting the Fox hit's Sept. 21 premiere, Mercedes, Artie and Mr. Schuster have their sights set on making it to this year's national competition in New York City.

How will they pay homage to the Big Apple? By covering Jay-Z and Alicia Keys' "Empire State of Mind," of course!

"They say we only sing showtunes and 80s pop -- let's show them how down we are," enthuses Matthew Morrison's Schuster.

Watch the clip above to see the gang don their best streetwear for a practice session.

The season premiere of Glee airs Sept. 21 at 8 p.m./ET on FOX.
