If there were ever a time to get freaky, it’s the holidays. Spinning, flipping, dashing, and dancing through Detroit, once again, is Cirque Dreams Holidaze, part musical theater and part Vegas-drenched acid trip, where visions of sugarplums dance in proximity to your head. The performance hosts 20 acts, with dozens of performers donning more than 300 dazzling costumes (the oversized gingerbread people are particularly … stirring) and a slew of original holiday songs and a bunch of familiar ones, too. A multimillion-dollar production with never-before-seen performances features elaborate sets and displays and lots of mind-melting acrobatics.
