Judah Adashi, of the Peabody Institute, has put together a program of ground-bass works across the centuries, to transpire on Sept. 30 at Peabody. It includes his beguiling new piece my heart comes undone, inspired by a phrase of Björk's. Lavena Johanson is the cellist on the recording. I'm delighted to have provided a bit of inspiration for the concert, with my old "Chacona, Lamento, Walking Blues" essay.
