I have an album of 19 piano improvisation pieces out now. Some of them are from 50/90 this year others are brand new.
I used Distrokid which means its been put on Spotify, Apple Music, YouTube, etc. It's also on Bandcamp here https://roddy.bandcamp.com/album/piano-improvisations
All the positive feedback from 50/90 users was a big help in encouraging me to complete this project.
