By now, Bostonians are familiar with the near-annual sight of the blue and yellow tent of the famed Canadian performing outfit Cirque du Soleil. Those not spying that colorful, temporary structure this year need not be disappointed, however, as Varekai —Cirque du Soleil’s dazzling show following the adventures of Icarus, a young man who finds himself in an enchanted forest filled with fantastical creatures—sets up at Boston University’s Agganis Arena from July 15–19 this time around. Expect eye-popping sets and costumes—along with plenty of acrobatic wizardry from an array of clowns, jugglers, trapeze artists, dancers and more—at this extravaganza inspired by the nomadic souls of the gypsies.
