Eric Alfred Leslie Satie (born 17 May 18661 July 1925), better known as Erik Satie, was a French composer and pianist. The son of a French father and a British mother, he studied at the Paris Conservatoire but was undistinguished and did not obtain a diploma. In the 1880s he worked as a pianist in café-cabarets in Montmartre, Paris, and began composing works, mostly for solo piano, such as his Gymnopédies and Gnossiennes. He also wrote music for a Rosicrucian sect to which he was briefly attached. Wikipedia
