DirtDay! is a remarkable piece of performance art. The stage is lit with candles as Laurie Anderson begins a musical journey punctuated with spoken thoughts on the role of women, evolution, religion, politics, philosophy, economics, death - with superb dramatic timing and plenty of humour. This show has so many levels - a visual feast, a philosophical treatise, an entrancing musical performance, and at times a profound literary event. While Anderson reveals her depth as a serious artist in choreographing the multiple facets of this performance, it is also liberally sprinkled with opportunities to appreciate both the absurdity of existence, and her own art. Her dog gets a cameo role as a guest artist! There were shades of Pink Floyd and Nick Cave in the hypnotic feel of the musical score but the mastery of electronic keyboard, violin and other assorted gadgets produces an overall sound that is uniquely hers.
