Time Out New York called "Traces" at Union Square Theatre "a thrillingly modern brand of circus with a street-smart twist." Select seats are now $38.50 (regularly $78) for all performances through Sept. 9.

Set to a rock 'n' roll soundtrack, "Traces" combines awe-inspiring acrobatics with infectious urban energy. Throughout the show, traditional acrobatics are combined with street elements like skateboarding and basketball. Time magazine named the show one of the Top 10 Plays and Musicals of 2011, and The New York Times says it's "a fix of pure urban adrenaline."

Note: Due to the popularity of this deal, some performances may be sold out.

The Los Angeles Times says it best: "Somewhere between your eye and your brain, logic gives up. There are some physics Stephen Hawking can't even explain."
