The Orchestra's first recordings were made for the Victor Talking Machine Company in Camden, New Jersey, in 1917, when Leopold Stokowski conducted performances of two of Brahms's "Hungarian Dances". The historic first electrical recordings were also made by Victor in Camden, in April 1925, beginning with Saint-Saëns' "Danse macabre". Later, in 1926, Victor began recording the Orchestra in the Academy of Music. Stokowski led the ensemble in experimental long-playing, high-fidelity, and even stereophonic sessions in the early 1930s for RCA Victor and Bell Laboratories. They recorded the soundtrack for Walt Disney's "Fantasia" in multi-track stereophonic sound in 1939–40.
