Ensems
Ensems (, meaning "jointly, at the same time") is an annual contemporary classical music festival that takes place every spring in Valencia. Founded in 1978, it is the oldest contemporary music festival in Spain. It centers mostly in chamber music due to budget restrictions.
Works by composers such as John Cage, Elliott Carter, Brian Ferneyhough, Hans Werner Henze, Helmut Lachenmann, Krzysztof Penderecki, Salvatore Sciarrino or Iannis Xenakis have been given their Spanish premiere throughout the festival's history.
