It was 1970. I was a student in Warsaw. Once a week our composition class would gather at the Academy for an analysis course. We were an odd bunch, a Hungarian pianist, a black Cuban composer, a conductor, two spirited Polish girls, and myself. But we were also typical of the sort of international group that had assembled in the Polish conservatoires at that time—musicians brought together by a common fascination with the Polish School, which was still very much in full flight, and by a determination to unravel its technical and aesthetic mysteries.
