"Paris" by David Stevens With the home team showing off in the U.S., the Paris opera season was launched by Robert Wilson's and Philip Glass' "Einstein on the Beach," given nine performances at the Opera Comique under the avant-garde aegis of the Festival d'Automne and the Semaines Musicales Internationales de Paris. "Einstein" is an opera mainly because Wilson and Glass say so, but more convincingly because it has a score by Glass that runs for the full four-and-a-half hours plus, contributing powerfully to the work's cumulative mystical-mesmeric-dramatic effect. There is no chance for conventional vocal display - the principal performer, Lucinda Childs, is primarily a dancer - but most of the seventeen listed actors double or triple as dancers and choral singers; the eight musicians include a woman vocalist. "Einstein" is a dreamlike, almost bubliminal study of themes from the life and times of the great scientist. There are some overt references - notably a violinist (Robert Brown), made up as Einstein, who has some extended cadenzas to play - but many more are addressed to the subconscious. The work moves in an inexorable "lentissimo," animated by a proliferation of mini-events, a huge theatrical machine propelled by feverishly spinning inner parts. The music, played by Glass' own ensemble in his established idiom of a busy succession of notes suspended in static and repetetive patterns, had a quasi-Oriental hypnotic effect that aptly complemented Wilson's slow-motion time scale. The musicians occasionally joined in onstage. The basic structure is of three visual images seen three times each in various transformations for a total of nine scenes, divided into four acts and further separated, or articulated, by five intermezzo- like transitions that Wilson calls "kneeplays." The images are a train - a large cartoon locomotive that appears at the beginning and the end, a rear view of the train disappearing in the distance, finally its transformation into a building inside which a character feverishly does calculations; a trial scene with jury, wigged judges, witness box and an immense glowing bed that finally soars slowly into the flies; finally a field and spaceship - at first the field is full of dancers whirling dizzily with flower-child exuberance (choreographer Andrew de Groat) as the spaceship hovers above, evolving into a dehumanized fantasy interior of the spaceship. A kind of climax is provided by a drop curtain that seems to represent a nuclear explosion, suggesting Nevil Shute's "On the Beach" as a title reference, but it is softened by idyllic kneeplay. At the October 6 performance, the Halle Favart was well filled with a relaxed and attentive audience. Spectators would walk out for an intermission not offered by Wilson and Glass, then return, sometimes applauding one or another of Wilson's stage effects (some of which severely taxed the Comique's resources) and rewarding all with a warm ovation.
