Revised Schedule

Owing to an unusual pileup of teaching obligations, I have re-scheduled today’s post, “Notes on Porgy,” to Sunday, Nov. 3. It examines the Gershwins’ and Heywards’ unique work, its problems of form and the controversies that often accompany it, in the light of the Metropolitan Opera’s ambitious new production. Apologies for the delay.
