Tandabase has thousands of golden-age tango recordings catalogued. Most of them already have a YouTube video attached so they play out of the box when you build a set. The rest, well, that's the work. This page tracks where we are. The goal is 100% across every orchestra.
You can help: when you spot a wrong or missing video while listening, click "wrong video" in the player and paste a better one. Every fix gets reviewed and rolled into the database. How this works.
