Find a recording you know nothing about and see if you can discover any information about it. If you're unable to find anything of significance, such as a Wikipedia page, Pitchfork article, dedicated blog, etc., then create a historical record for your recording. The less information you find for your record the better. You should research all aspects of your recording for information, e.g., artist, production, songs, packaging, etc. The historical record you create should both introduce the recording to your audience and also offer any new information you've uncover. You may present your final record as a single piece or build it as an archive over time. Your selection can be recorded in any format.
