One of Cirque Du Soleil's most accessible projects, DELIRIUM is a multimedia event designed to be more of a pop concert than a circus performance. The production draws largely from music featured in past Cirque Du Soleil shows, but the performers here rework the material in intriguing ways. "Nova Alegria," for example, turns the theme of ALEGRIA into a lilting Latin-tinged tune, and "Lifeline" adds dance floor rhythms and a brighter sheen to "El Pendulo" from VAREKAI. For those who value Cirque Du Soleil's music as much as its stunning visuals, DELIRIUM is essential.
