History of Electro

Experimental/ambient electronic music started in the 50s, but here, I want to showcase the roots of electronic dance music, which needs beats. Most of these milestones, especially '1st track of a style', are discussed controversially, but these are good examples, i.m.h.o.
Deep House Key Art
Ordered by key ascending > bpm ascending

1st number + character, e.g., 1A to 12B: musical key (major/minor) for harmonic mixing in Camelot notation.
2nd decimal number, e.g., 114.5: beats per minute.
