I couldn't find an answer on google - how is a goat farm precursor for music? It's an activity that needs herding and shepherds started playing songs for fun? Or..? :o

It's an old story about using a drum machine and feeling like it's not real music, replacing the synthesized samples with real drum samples, then getting rid of the machine playing the drums yourself, then making your own drums, then finally farming your own goats for leather to make drumheads out of.

Stringed instruments use goat or sheep intestines. And drums are from their skin (leather).
