[3][7] The Ensemble intercontemporain was founded in 1976 by composer and conductor Pierre Boulez, with the support of French Minister of Culture Michel Guy and the collaboration of Nicholas Snowman,[3][8] in order to provide performers for contemporary chamber music.

[1][4] The idea for the Ensemble came from Boulez's experiences as part of the historical avant garde of Darmstadt, Germany, in the 1950s, contemporary of Stockhausen, Berio, Ligeti and Nono.

In December 2021, the EIC announced the appointment of Pierre Bleuse as its next music director, effective with the 2023–2024 season, with an initial contract of 4 years.

[13] The Ensemble has toured extensively to South America, Russia, Canada, the United States, Japan, New Zealand, Australia, and most major cities of Europe.

[7] Recent performances include the National Autonomous University of Mexico and the Palacio de Bellas Artes (2007),[6] Buenos Aires in 2012,[14] the Festival Internacional Cervantino in 2014,[5][15] and in honor of Pierre Boulez's 90th birthday, a concert at the Barbican Centre in London.
