Iron Foundry
At the Hollywood Bowl in 1931, "Iron Foundry" was used as the music to Adolph Bolm's ballet, "The Spirit of the Factory"—known also as "Ballet mécanique" (not to be confused with the 1924 composition by George Antheil), "Mechanical Ballet", and "The Iron Foundry"—which opened to "rousing ovations, rapturous reviews, and popular demands" for an encore performance. This was the first time "Iron Foundry" was performed for a stage performance, although it was never staged as originally intended.
