...It's quite a composition. I'm pretty sure Baxter got his inspiration after working on those groundbreaking Yma Sumac albums of the early 1950s, as well as the LPs of theremin music written by Harry Revel and played by Dr. Samuel Hoffmann.
"The Passions" also came right between Baxter's first two exotica LPs, "Le Sacre du Sauvage" and "Tamboo!"
In fact Les Baxter wanted to make the Passions concept album with Yma Sumac but she turned it down and went to do Mambo with Billy May instead.
