3 weeks ago Marc A. Pullen would be a good addition (all albums are CC BY-SA).
Cloudkicker has all their albums uploaded before 2020 under CC BY, but albums uploaded after that are CC BY-NC-SA.
It's been a while, but I'd love to hear some new music from anyone releasing stuff under a Creative Commons Attribution or Attribution-ShareAlike license. If you have anything to suggest, please leave it as a comment with a link to buy/stream/download.
