Here's a description from the Jim Henson Company:
“Drums West” cut-paper animation from Jim Henson. This newly rediscovered short was created in Jim’s home studio in Bethesda, MD around 1961. It is one of several experimental shorts inspired by the music of jazz great Chico Hamilton. At the end, in footage probably shot by Jerry Juhl, Jim demonstrates his working method.
It reminds me a lot of Disney's Fantasia's elements that visualize the music combined with a pre-Sesame Street homegrown animation feeling. And I love the adorable shot of Henson (pre-beard, notes my husband) at the end.
This also feels very appropriate right now because it's raining outside and the music reminds me of rain on a tin roof. Staccato, like fireworks, yet somehow soothing.
