London Moods (1961)

Ken Russell is often cited as one of the fathers of the music video, with Tommy (1975) widely recognised as one of the pivotal works in the development of the form. However, as the far more obscure Monitor item London Moods from 1961 proves, he was experimenting with non-narrative illustrations of pre-recorded music fourteen years earlier.

Unfortunately the movie London Moods is not yet available on HBO Max.
