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.
