Louis Joseph Andriessen 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. 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.

The Royal Conservatoire is a conservatoire in The Hague, providing higher education in music and dance.

Since September 2021, the KC is housed in the Amare building in the centre of the Hague, together with the Residentie Orkest and the Nederlands Dans Theater (NDT).
