As for female songwriter-y records

I thought the subject was uneven output. As for the female songsmiths...

My favorite obscure ones are all by women with very small output:
Karen Dalton, It's So Hard to Tell..., friend of Fred Neil and Bob Dylan
Erica Pomerance, You Used to Think, drugged out, meandering, theatric disaster (in a good way, I swear)
Linda Perhacs, Parallelograms, floaty and light, nice

Between the 3, I only know of one other record (Karen Dalton made a second)
