Despite his rigorous classical training, Altschuler was not averse to modernist experimentation. The Symphony's March 1915 New York premiere of Alexander Scriabin's Promethee: Le Poeme de Feu (Prometheus: The Poem of Fire) with Marguerite Volavy as pianist, featured a newly invented device, the chromola, which rendered musical tones in color.[4][5]
After disbanding the orchestra on the eve of the first World War, Altschuler moved to California, where he built a notable reputation as a teacher and performer. With help from his cousin, film executive Joe Aller, he composed and performed in film scores, including The Sea Hawk (1924), Dawn to Dawn (1933), It's All in Your mind (1938), Buffalo Bill Rides Again (1947), and Song of My Heart (1948), He was also active in southern California's musical community. In 1926, he organized the Glendale Symphony Orchestra.[6]
