Ex Machina is a collaboration between saxophonist/composer Steve Lehman, whom the New York Times has called "a state-of-the-art musical thinker," and Orchestre National de Jazz (ONJ) that goes far beyond anything attempted before by a jazz big band. Featuring compositions by Lehman and Frédéric Maurin, ONJ's artistic director, the work incorporates elements of French spectral harmony into it's compositional framework while also integrating live, interactive electronics developed at IRCAM in which abstract electronic sounds react to soloist improvisations in real-time. The new work is inspired by Lehman's Octet, whose groundbreaking work were the first to utilize spectral harmony's complex sonorities within a jazz context. Their critically-lauded releases Mise en Abime (Pi 2014) and Travail, Transformation and Flow (Pi 2009) were voted the #1 album of the year in the NPR Jazz Critics Poll and the #1 jazz album of the year in The New York Times, respectively.
