This book is a somewhat rough but the event (note in the video that Justice Black was there) -- 75 years ago -- is a striking social and music moment. D.A.R. blocked black performers at their "Constitution Hall" and the D.C. school system (after controversy) only would only allow her with troublesome conditions. Lemons from lemonade! The book provides a biography (a rich one; not enough provided of her internal life) and shows how this (including her special dignity) was an early civil rights moment that was a preview for what was to come.
