In the fall of 1935, Headley joined the music department of Fresno State College, replacing Assistant Professor Arthur C. Berdahl.[4] Although he had produced and performed various short compositions on violin, piano, and organ since the 1920s, his first work to receive national attention was The Jester's Dream, a symphonic composition completed in the summer of 1935, and subsequently performed by the Chicago Symphony Orchestra.[4]
Also in 1939, Headley joined the faculty at Santa Barbara State College, and succeeded Maurice Faulkner as conductor of the University of California Symphony Orchestra in Santa Barbara.[9] Here he began to hone his reputation as a composer and pianist, giving various concerts at which he conducted his own works.[11]
In 1942, José Iturbi conducted the premiere of Headley's Argentango, a concerto for piano and orchestra, with the Rochester Philharmonic Orchestra.[12][13] Later that year, Headley performed a "piano sketch" of what would eventually become his Symphony No. 2, Prelude to Man, based on the poem by Chard Powers Smith, about the stages of the development of life on earth prior to the advent of mankind.[12] The work would not be completed until 1951, at which time Headley took it to New York to present to Howard Hanson, Leonard Bernstein, and other leading figures in the musical world.[9]
Headley enlisted in the United States Army Air Forces in January, 1943, training to become a transport pilot during World War II, and receiving military leave from Santa Barbara State College.[11] After his wartime service concluded, the U.S. State Department asked him to report on the familiarity of Europeans with American cultural life during a visit to France and England. Based on his experiences, Headley concluded that Europeans were most familiar with American culture through Hollywood films and Swing music, and recommended that funds be expended to acquaint them with the nation's other cultural developments.[14] Headley subsequently gave performances in Paris, London, Budapest, and Prague.
In 1948, Headley was invited to serve as guest conductor of the Standard Symphony Hour, which had regularly performed his compositions.[15] He continued to premiere new works into the 1950s.[16][17] He was named conductor of the Fresno Municipal Symphony Orchestra, and was also a guest conductor of the Duluth Symphony Orchestra.[3]
By the late twentieth century, Headley's music was largely forgotten, and many of his works are lost. In 2006, his music resurfaced by accident. For the one hundredth anniversary of his birth, Russian State TV performed several of Headley's compositions, including the California Suite, conducted by Dmitry Yablonsky, a conductor who has focussed on reviving forgotten or hitherto unknown music. In 2007, Robert Buckley, one of Headley's former students, and Stan MacDaniel took joint responsibility for the recordings of his music. Subsequently, the Naxos record label published a CD of Headley's music in an "American Classics" series.[18]
