I realized that I forgot to mention the theremin in the Rocketman recording. It’s an amazing musical instrument, unfortunately often limited in public perception to old ’50s scifi movie sounds. It’s currently enjoying a rebirth in popularity and interest on the Internet, although only a few theremins remain in existence. Howard Mossman, the father of my friend Jan Mossman from high school, is a well-respected figure in the theremin community (here’s a pic of Mr. M with one of his theremins, about 9 pics down on the page).
In the Rocketman recording you can hear the theremin if you listen, especially twenty seconds before the end where the musician lets out a ’50s scifi movie riff with the instrument.
