Ancient Greece had a device called the "brazen bull." It was a live-cremation device which doubled as a musical instrument. It was a brass bull statue about the size of a pickup truck with an empty chamber in its belly large enough for a human body. Anyway, the victim was loaded into the "combustion chamber" and locked in. Then they'd light a giant fire under the bull's belly to slowly roast the poor bastard to death. And here's where the grotesque part comes in: the bull's combustion chamber had an air pipe leading to the bull's nose that was shaped and angled in such a way, it converted the victim's screams into brass instrument sounds blowing out the bull's nose, not unlike a tube or french horn. So the more the victim screamed, the more the brazen bull sounded like a brass musical section.
