Cirque Du Soleil's 'Alegria'

Happiness, joy, and jubilation are what it's all about at Cirque du Soleil's "Alegria," which is a Spanish word for those three upbeat emotions, plus the name of the show's imaginary kingdom. But that's not the whole story at these ethereal, dreamlike productions. The deeper meaning involves power vs. weakness, the king vs. his jesters, change vs. certainty, and age vs. youth. -- June Wulff, Globe Staff
