The human body is a bag of meat and bones.

Chompers bared, their facial movements emit the sound of enamel on enamel.
When the afflicted are quarantined together, the resulting sound is like the clattering of steel locusts in hell.
Its really experimental, the veteran ofBreaking Bad,Mozart in the Jungle, andFargotells Vulture.
If you have an idea and you wanna try it, you go for it.
Initially, Forshagers team tried the most obvious direction: on-set sound from the actors playing the diseased folks.
They actually recorded the microphones on the people as they were chattering their teeth, he says.
My sound designer tried things like horse hooves, Forshager recalls.
Next, Forshager turned to people whod never appeared in front of a camera or a microphone before.
Id walk around the office, saying, Chatter your teeth.
Let me hear what it sounds like.
Some people, they were fully volunteering to do it.
And some people, well, its hard on your teeth.
It actually kind of hurts after doing it.
Still, Forshager couldnt quite nail what he wanted.
The final step was distorting the gathered sound.
Et voila, the terror of the human skull.
As for Forshager himself, dont think he merely stood on the sidelines.
He included himself in the process, having recorded his own teeth chattering too.
Ill definitely say my jaw was a little sore, he recalls.
My teeth were a little sore.
But Forshager assures me it was all worth it.
When you see it finished, it really, every time, makes me pop up.
It makes me cringe a little bit.
