This is an early neoclassical piece that would later come to be known as This Town is a Sealed Tuna Sandwich, in the film 200 Motels.
If you're interested in hearing more of Frank Zappa's challenging and often heartbreakingly beautiful orchestral compositions, I highly recommend getting your hands and ears on a copy of The Yellow Shark. Start with the track Outrage at Valdez.
Bon Weekend, everyone.
Also at Cogitamus.
