I have read several articles that listed Gustav Holst as the grandfather of all movie soundtracks. This is certainly true of “space opera” films; before there was John Williams, there was Holst. The English composer’s Planets suite is the definitive composition for our neighbors in the solar system.
Here, you can listen to “Jupiter, the Bringer of Jollity” from The Planets.
“Jupiter” is my favorite part of The Planets; the father of the gods deserves the best.
