This is Elliott Carter's Double Concerto for Harpsichord, Piano and Two Chamber Orchestras.

(MUSIC)

He began his musical studies at Harvard University in the nineteen thirties and went on to study in Paris.

His early works were influenced by composers of the classical period of the late seventeen hundreds and early eighteen hundreds. But he later broke away from this neoclassical sound to create a freer and more expressive modernist sound.

Elliott Carter has written over one hundred thirty works, many of which he composed after the age of ninety. He is one hundred one years old.

(MUSIC: ''Facades"/Philip Glass)

VOICE ONE:

Philip Glass performs one of his works before the Dalai Lama is introduced at the University at Buffalo in New York in September 2006.

The music of Philip Glass is often described as minimalist, though not by him. He would rather people describe his music as having repeating structures.

Philip Glass experiments with many different sounds. He has written operas, concertos and symphonies. He has worked on projects with singers, dancers and artists. He has also written music for many movies, including "Koyaanisqatsi," "Kundun" and "The Hours."
