Deus ex Machina is a piano concerto by the American composer Michael Daugherty.
The 33-minute work was jointly commissioned by the Charlotte, Nashville, New Jersey, Rochester and Syracuse Symphony Orchestras.
It won the 2011 Grammy for Best Classical Contemporary Composition for a recording by soloist Terrance Wilson and the Nashville Symphony Orchestra under the baton of Giancarlo Guerrero.
Deus ex Machina was recorded and released on Naxos along with a work from earlier in Michael Daugherty's career, the Metropolis Symphony.
"[2] Each of the three movements of the piano concerto is a musical response by the composer to the world of trains.
