Philip Glass (born January 31, 1937) is an American composer. He is widely regarded as one of the most influential musicians of the late 20th century.

Glass's compositions have been described as minimal music, similar to other "minimalist" composers including La Monte Young, Steve Reich and Terry Riley.However, Glass has described himself instead as a composer of "music with repetitive structures",which he has helped evolve stylistically.

Glass founded the Philip Glass Ensemble, with which he still performs on keyboards. He has written numerous operas and musical theatre works, eleven symphonies, eleven concertos, seven string quartets and various other chamber music, and film scores. Three of his film scores have been nominated for Academy Awards.

Glass has composed many film scores, starting with the orchestral score for Koyaanisqatsi (1982), and continuing with two biopics, Mishima: A Life in Four Chapters (1985, resulting in the String Quartet No. 3) and Kundun (1997) about the Dalai Lama, for which he received his first Academy Award nomination. In 1968 he composed and conducted the score for director Harrison Engle's minimalist comedy short, Railroaded, played by the Philip Glass Ensemble. This was one of his earliest film efforts. Glass's music was featured in two award-winning films by Russian director Andrey Zvyagintsev, Elena (2011) and Leviathan (2014). For television, Glass composed the theme for Night Stalker (2005).
