On today’s date in 1940, Disney's animated film Fantasia opened at New York's Broadway Theater.

Disney’s film was a milestone in cultural “cross-over”, in which classical music – in the person of conductor Leopold Stokowski – shook hands (literally and figuratively) with pop culture – in the person of Mickey Mouse.

It was also a milestone in cinematic sound. For its initial East and West Coast release, the Philadelphia Orchestra recorded nine special tracks, one for each section of the orchestra. These were mixed by Stokowski into a 4-track stereo soundtrack to be played in synchronization with the film on special equipment made by RCA for a multiple-loudspeaker theater installation called "Fantasound.” Three large speakers were positioned behind the projection screen, and no fewer than 65 smaller speakers were placed around the walls of the theater.

The resulting “surround-sound” was stunning by 1940 standards, but cost $85,000 to set up. After the 2nd full installation at the Carthay Circle Theater in Los Angeles, “Fantasound” was not employed anywhere else. Instead, eight reduced "Fantasia Road Show" speaker set- ups toured American movie theaters until 1941, when, following the outbreak of World War II, Disney diverted his funds, technology, and even Mickey Mouse toward the war effort.
