Louis Andriessen (Dutch pronunciation: [luˈi ˈɑndrisə(n)]; 6 June 1939 – 1 July 2021) was a Dutch composer, pianist and academic teacher. Considered the most influential Dutch composer of his generation, he was a central proponent of The Hague school of composition.[1] Although his music was initially dominated by neoclassicism and serialism, his style gradually shifted to a synthesis of American minimalism, jazz and the manner of Stravinsky.
