Alegría is a mood, a state of mind. The themes of the show, whose name means "jubilation" in Spanish, are many. Power and the handing down of power over time, the evolution from ancient monarchies to modern democracies, old age, youth - it is against this backdrop that the characters of Alegría play out their lives. Kings' fools, minstrels, beggars, old aristocrats and children make up its universe, along with the clowns, who alone are able to resist the passing of time and the social transformations that accompany it.
The lively and emotional musical score moves between jazz, pop, tango and klezmer. The band evokes the sound of traveling minstrels by using acoustic instruments, including an accordion, as well as the gravelly and genuine voice of the street. But in counterpoint the synthesizer arrangements also reflect the change that is imminent. The Alegría soundtrack is the best-selling Cirque du Soleil album to date.
