Gian Carlo Menotti Gian Carlo Menotti (] ; July 7, 1911 – February 1, 2007) was an Italian-American composer and librettist. Although he often referred to himself as an American composer, he kept his Italian citizenship. He wrote the classic Christmas opera "Amahl and the Night Visitors", along with over two dozen other operas intended to appeal to popular taste.
Gustav Mahler Gustav Mahler (] ; 7 July 1860, Kaliště, Bohemia, now Czech Republic – 18 May 1911, Vienna, Austria-Hungary) was an Austrian late-Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th century Austro-German tradition and the modernism of the early 20th century. While in his lifetime his status as a conductor was established beyond question, his own music gained wide popularity only after periods of relative neglect which included a ban on its performance in much of Europe during the Nazi era. After 1945 his compositions were rediscovered and championed by a new generation of listeners; Mahler then became one of the most frequently performed and recorded of all composers, a position he has sustained into the 21st century.
