Aw, come on. Fess up. You know you've done it when nobody's looking - stood in front of a mirror and conducted your favorite Mahler or, at least, played air guitar.
In 2007, Xavier Le Roy turned his "conducting" of a recording of Le Sacre du Printemps into a marvelous dance performance. He's taken this concept to another level with More Mouvements, not so much choreographing on the musicians in the piece, but allowing the music (or the score) to impel the movement, which looks more like pantomime than dance, especially when the instruments have gone missing and/or are hidden with musical doubles playing them behind screens.
