Support Vinilkosmo And Receive Almost Every Esperanto Music Album
Vinilkosmo is the record label that produces pretty much all the Esperanto music albums. However, sales of physical records are declining so instead they are switching to an online system. If you support them through the French version of Kickstarter/Patreon for as little as €10, you get to receive their entire collection of music albums for a year. So if you want to listen to Esperanto music and discover artists, I can't think of a better way.

There are more than 100 Esperanto albums available and thousands of other artists too. I highly recommend it.
