Radio supplies me with lots of random artists I would otherwise not know about( I’m lucky that I live in a market with two public radio stations, a great jazz station and a great classical station).
Radio Paradise is another good source.
I also have a close friend who’s mother was a concert pianist/composer/broadway musical writer and he has been a great source of artists.
And then there is YouTube. In between my searches for DIY audio how too’s, gear reviews and news stories, there will be some random artist that shows up in my feed. Beth Hart was a recent “discovery” for me.
Sometimes, it’s just about letting the randomness of the universe express itself.
