A vociferous response from the audience drew an encore from Gomyo -- a little more than one, actually. She started playing one of the Tango-Etudes by Astor Piazzolla (the energetic No. 3, I think), then suddenly stopped, laughed and said, "I didn't practice that. I'm sorry." No harm done, for she quickly switched to the bittersweet Etude No. 4 and delivered it most eloquently.
