Philip Glass (born January 31, 1937) is an American composer and pianist. He is widely regarded as one of the most influential composers of the late 20th century. Glass's work has been associated with minimalism, being built up from repetitive phrases and shifting layers. Glass describes himself as a composer of "music with repetitive structures", which he has helped evolve stylistically. Glass founded the Philip Glass Ensemble, which is still in existence, but Glass no longer performs with the ensemble. He has written fifteen operas, numerous chamber operas and musical theatre works, fourteen symphonies, twelve concertos, nine string quartets and various other chamber music, and many film scores. Three of his film scores have been nominated for an Academy Award. Life and work 1937–1964: Beginnings, early education and influences Glass was born in Baltimore, Maryland, on January 31, 1937, the son of Ida (née Gouline) and Benjamin Charles Glass. His family were Lithuanian-Jewish emigrants. His father owned a record store and his mother was a librarian. In his memoir, Glass recalls that at the end of World War II his mother aided Jewish Holocaust survivors, inviting recent arrivals to America to stay at their home until they could find a job and a place to live. She developed a plan to help them learn English and develop skills so they could find work. His sister, Sheppie, would later do similar work as an active member of the International Rescue Committee. Glass developed his appreciation of music from his father, discovering later his father's side of the family had many musicians. His cousin Cevia was a classical pianist, while others had been in vaudeville. He learned his family was also related to Al Jolson.Glass's father often received promotional copies of new recordings at his music store. Glass spent many hours listening to them, developing his knowledge and taste in music. This openness to modern sounds affected Glass at an early age: The elder Glass promoted both new recordings and a wide selection of composers to his customers, sometimes convincing them to try something new by allowing them to return records they didn't like. His store soon developed a reputation as Baltimore's leading source of modern music. Glass built a sizable record collection from the unsold records in his father's store, including modern classical music such as Hindemith, Bartók, Schoenberg, Shostakovich and Western classical music including Beethoven's string quartets and Schubert's B
