Elevator To The Gallows (1958) score was composed and performed by Miles Davis in a one session recording while he watched a screening of the film. He took notes while watching the rough cut and then invited 4 fellow musicians without preparation to record it in one go. Genius.
"I think Ford was probably the first director I remember hearing about from my parents. “John Ford, John Ford, John Ford. He was a good director.” They thought highly of him based on 'The Grapes of Wrath' (1940) & 'How Green Was My Valley' (1941)"
