Pierre Boulez, the French composer and conductor whose career spanned from the avant-garde post-World War II era to the computer age, has died, according to the French culture ministry. He was 90. Boulez famously challenged his peers and his audience to rethink their ideas of sound and harmony.
In his music, Boulez often created rich and contrasting layers that were built on musical traditions from Asia and Africa, and on the 12-tone technique pioneered by Arnold Schoenberg — as in his 1955 work, Le Marteau sans maître (The Hammer Without a Master).
“I see music as a kind of continuity, like a big tree,” Boulez told NPR in 2000. “Of course there are many branches, many different directions. I think music is in constant evolution, and there is nothing absolutely fixed and rigidly determined.”
NPR’s Tom Huizenga cited the quote in a piece last year examining the composer’s rebellious roots: Boulez once disrupted a Stravinsky concert, and later said that opera’s problems could be solved by blowing up opera houses.
