An artist I always like to recommend is Molly Drake (Nick Drake's mom) who wrote some incredibly unique music, all home recorded in the 60s. I like to say it sounds like Mary Poppins on anti-depressants.
Then maybe Tucker Zimmerman? Singersongeriter active since the 60s who just released a new album made in collaboration with Big Thief.
If you wanna try recent things, I find Allegra Krieger and Naima Bock two awesome singer songwriters
