Physical theatre is better practiced or seen than read about. Lecoq himself apparently acknowledged this reality, since his only book on the subject of his own pedagogy was not published until shortly before his death. Nevertheless, Murray does an excellent job of placing Lecoq's work in the context of Western performance tradition, current theoretical models of the body and culture, and of examining the creative journeys of a pair of theatre companies based in his . . . . well, I don't really want to call it a "method" . . . let's just just say, "based in his explorations of the performing body." For someone aware of Lecoq and interested in pursuing training in physical theatre, this makes an excellent first dive into the waters. Murray even provides you with a sense of what the pedagogical method in a Lecoq-based program will probably be like, and some exercises used in class.
There's not a lot out there on Lecoq yet, in terms of the printed word, but there are now a number of theatre companies and well-known performers and directors (Theatre Complicite, Mummenschanz, Theatre de la Jeune Lune, Bill Irwin, Julie Taymor and most of the "clowns" of the Cirque de Soleil, to name only a few) working with the inspiration Lecoq provided and, as they continue to achieve prominence in the culture, more and more will be written about Lecoq as a result.
