Can't help you about Dede, at the moment. But Carter Pann wrote at least
one other work besides a piano concerto (which I took to be a misprint, at
first, for Carter's piano concerto- bad Eric!)- Barcelona Portraits, I
think- available in a library in Ohio...

[I can find reference to a female composer by the name of Dede Duson. Her
works appear to be mainly choral in nature, and she is probably still with
us. -Dave]
