Judee Sill
The New York Times is performing a wonderful service in its series of obits running under the title Overlooked. They are op-eds of men and women whose deaths received no notice when they were alive because they were female, a person of color, or some other under-served and marginalized group.
They begin in 1851.
Their most recent is of the folk musician Judee Sill. Sill died in 1979 of a heroin overdose, but she was among the greats of her generation, just not recognized as such or as much as she deserved.
I urge you to go to Spotify and listen to her work. Beautiful.
Below is just one example from YouTube:
