I dislike the linearity of your lineage. Misses out the kind of obvious ones like e.g. The Beatles looping tapes and building on Musique Concrète.

Pretty much! Musique Concrète basically starts with the invention of magnetic tape. Electronic music itself basically starts with the vacuum tube.

Humans just really like making new sounds and music. If we invent any new tech that makes an odd noise, there will be a bunch of stoned grad students jamming with it later that day.
