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.

Luciano Berio was an Italian composer noted for his experimental work, and for his pioneering work in electronic music. His early work was influenced by Igor Stravinsky and experiments with serial and electronic techniques, while his later works explore indeterminacy and the use of spoken texts as the basic material for composition.
