Thanks a lot Luther! I really appreciate that. Yeah pastiche can get tired really quickly, it's cute to play spot the influence but if they aren't there in service of an urgent idea, then you're just looking at prettily cloaked air
The skello is basically patterned off a cello (although the tuning is significantly different), constructed out of steel, with a long tall neck and a creepy skeletal rib cage that acts as the back of the instrument. It's very quiet unamplified but is outfitted with a contact mic apparatus and plugged into an amp (in this case). It's Caleb's first instrument, and is not that useful as a melodic voice, but man you can achieve some creepy drones on it!
actually, here's a picture of Caleb with the cello:
