The Wikipedia article of the day for August 29, 2017 is Nikolai Rimsky-Korsakov.
Nikolai Rimsky-Korsakov (1844–1908) was a Russian composer, a member of a group of prominent composers known as The Five, who worked together in Saint Petersburg in the mid-19th century. Considered a master of orchestration, his best-known compositions, which include Capriccio Espagnol, the Russian Easter Festival Overture, and the symphonic suite Scheherazade, are considered staples of the classical music repertoire, along with suites and excerpts from some of his 15 operas. Scheherazade is an example of Rimsky-Korsakov's frequent use of fairy tale and folk subjects; he also left a considerable body of original Russian nationalist compositions. His preparation of works by The Five for performance brought them into the active classical repertoire, although his editing of the music of Modest Mussorgsky created controversy. As a shaper of a generation of younger composers and musicians during his decades as an educator, he is considered the main architect of what the classical music public considers the Russian style of composition.
