Maybe there are some musicians I didn't find yet, but I support musician curating through @music-community, @curie, @la-colmena and @minnowsupport. You can check all the showcases of those communities and you will see how many musicians are getting my support. Inside all these projects we look for the things I mentioned in the previous comment.
If you see many other good musicians making a great job and not getting support, you should try to be part of one of those projects and support them.
I just answered the topic you wrote about...!
