February 23, 1972, WNET's program Soul had four pianist playing together. Jaki Byard, Hank Jones, Roland Hanna and Patti Bown. I never heard of her until I listened to the audio from this program. I'm not shy to admit I don't know everything about jazz. Anyone know more about her?
I came across this web page that mentions her.
