Members of a lineage of musicians and trained with Fauré and Saint-Saëns, the aptitudes of the sisters Nadia and Lili Boulanger astonished French musical life, dominated −as in all of Europe− by men. The premature death of Lili would deeply affect Nadia, who subsequently threw herself into teaching. There classes were filled with composers from the five continents who would later shape the history of the twentieth century. Mademoiselle, today considered one of the most important music teachers of all time, combined el rigor en her teachings with a tolerance of very different styles. This series, wholly performed by women in line with their spirit, combines works by these two women composers, pioneers of their time with works by some of their pupils (the majority of which were male) such as Copland, Menotti, Bernstein, Glass, Narcís Bonet and Astor Piazzolla.
