What do you get when you combine acrobatics, holiday music, and aerial performances? The answer: Cirque du Soleil's 'Twas the Night Before... holiday spectacular. This high-energy production will return to The Met Philadelphia for an 11-day run from Dec. 17 to 27. Featuring 26 performers from around the world, the show includes aerial straps, hoop diving, hair suspension, dance, and other gravity-defying acts, set to a reimagined Christmas soundtrack. As the PhillyVoice noted, the show is designed as a family-friendly, holiday-specific production, distinct from Cirque's touring arena shows.
