The history of recorded music, as a playlist
Five eras, told through the songs that changed how records get made. Every card is a first:
the first time a machine, a technique or an idea is audible on a record you can play in the room.
Teacher selection, not spec content. The spec names no tracks, artists or producers:
every choice here is a pedagogical one, and "first" claims in recording history are almost always
contested. Cards marked contested first carry the standard account and name the rivals.
Sits alongside the Era-ID listening drill (3.3), which trains the cues these songs demonstrate.
