In 2005, the National Gallery of Art in Washington, DC commissioned Lehrman and the League of Electronic Musical Urban Robots (LEMUR), Eric Singer, director, to create a computer-driven robotic ensemble to play the Ballet mécanique. This installation was at the Gallery from 12 March to 7 May 2006. It was installed in December 2007 at the Wolfsonian Museum in Miami Beach, FL, and again at 3-Legged Dog in New York City, where it was used to accompany a play about Antheil and Hedy Lamarr, and their invention of spread-spectrum technology, called "Frequency Hopping." During the run of the play, the Léger/Murphy film was shown, with the robotic orchestra performing the score, at two special "after-concerts."
