The Warriors: Music to an Imaginary Ballet is an orchestral piece written in the United States by the Australian-born composer and pianist Percy Grainger between 1913 and 1916. It is dedicated "For Frederick Delius, in admiration and affection".
In addition to the usual orchestral forces, it calls for a very large percussion section, including off-stage brass, led by an assistant conductor, and three pianos.
Critics were undecided as to whether the work was “magnificent”, or merely “a magnificent failure”.[1]
