I first met Judy in ~1973 when we were both members of The Quadrivium, an early music performing group. In 1978 she founded The Voice of the Turtle, a Sephardic music group of four talented musicians, all of whom had been members of The Quadrivium). They gave many local concerts as well as some internationally and made a bunch of CDs - all of which I have.
This group under Judy's leadership revived and extended a little known musical tradition. Sound clips of a few pieces are available on the web site.
My sympathies to her family and to her many friends. This is a big loss.
From the Song of Solomon:
The flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle is heard in our land.
