Hey Maddie, this is Steve from Crudlabs. Thanks so much for this awesome writeup! I appreciate that you called the sounds creepy and spooky... Possibly the single most appropriate use for the perpetually warbly, in-and-out-of-key sounds of the Crudman would be for a film scorer to use for atmosphere in a low budget…

Feels a lot like something the BBC Radiophonic Workshop might have used. Except they’d have done it by hand without the keyboard & using reel to reel tape decks.
