From Montreal comes Edouard Lock’s revolutionary and provocative contemporary dance troupe, LA LA LA Human Steps, which combines movement, live music, and film projections. Lock’s newest full-length work (as yet untitled) deconstructs, reconstructs, and adapts passages from two universally recognized operas, Purcell’s Dido and Aeneas, and Gluck’s Orpheus and Eurydice, set not to the music of the original operas, but to a new score by the British composer Gavin Bryars (played live). Lock calls his work a “contemporary reanalysis” in which he asks the question, can décor and film be used to advance narrative to an extent not desirable using choreography alone? You be the judge.
