History
The building was originally called The St. Louis Theater. It was built in 1925, designed by the Chicago architectural firm ofRapp & Rapp. The theater spent the first 40 years of its existence as a stage for livevaudeville performances as well as motion pictures. The last movie shown in the old theater was The Sound of Music in 1966. At that time, the building was acquired by the Symphony Society for $500,000, through a gift from Oscar Johnson, Jr.. After spending an additional $2 million to update and renovate the theater, the hall re-opened in January 1968 as the new home of the St. Louis Symphony Orchestra.

The building is said to be haunted by the ghost of a man named George. He is supposedly seen in a white suit and white hat and is thought to be that of a former vaudevillian. He is said to play with the lights and the elevators.
Carl Stalling, famous for providing the music to Warner Bros.' Looney Tunesanimated series, began his musical career as an organist at the St Louis Theater.

The St. Louis Children's Choirs is the official children's choir of the St. Louis Symphony.
