This is a good site for getting a primer into the roots of house… from which a lot of other genres including acid then developed.
NY Disco and Italo Disco helped provide influence to early house music like Z-Factor, Chip E, Sharivari & Jesse Saunders which was then echoed by the grittier acid in Chicago emerging about 5 years later.

I’m particularly interested in this era of music. 1982 seems to me to be the year when a lot of genre defining, mould breaking records were made which provided the bedrock for the next 5 or so years of genuine musical innovation. By the late eighties the ‘genres’ you’re seeking had already started to become clearly defined as formulas.
Every genre has classic tracks, but it’s often the early releases that have a level of energy and experimentation which gets dulled over time in my opinion.

Techno and electro arguably both started with Cybotron’s early releases as well as Planet Rock. Most of the techno pioneers started creating what they considered to be house music, but which then morphed into an entirely new genre. That’s my understanding anyway.
