Iannis Xenakis

April 26 | 8pm | Bard CPS

Concert Program


Plektó (1993)

Rebonds (1987-89)

Theraps (1975)

Bohor (1962)

Widely considered to be one of the most challenging and innovative composers of the 20th century, Iannis Xenakis (1922-2001) is that most rare artist who combines theoretical rigor and technical innovation with deeply personal, beautiful, and often terrifying emotional weight. This survey concert moves chronologically backward through his remarkable career, intertwining the
music and mythology of ancient Greece with an evocation of the many traumas of his early life.


Lacking any traditional notions of subtlety or musicality, Plektó (Braids, 1993) is one of Xenakis’s last works. The melodic lines among the winds and strings are woven around and through one another in extreme dynamics while the piano and percussion pound out dissonant chords and ritualistic rhythms. Most of the percussion music in Plektó is taken directly from the solo percussion work Rebonds (Rebounds, 1989) which is composed for a collection of drums and woodblocks that evoke frenzied, ecstatic ancient Dionysian rituals. The 1960s and 70s found Xenakis engaging with his demons more directly - although never explicitly - which seems particularly true of the double bass solo Theraps (1975). Loosely translated to English from ancient Greek  as “servant” or “healer,” the work’s extremes in register, dynamics, and physicality and its simultaneous, divergent glissandi suggest a duality of self in conflict. In ancient Greek, the word therapōn also refers to an Anatolian ritual of purification that, “expels pollution from the person to be purified” and Theraps does indeed feel like a sort of exorcism for both performer and composer.


The program concludes with an exceedingly rare opportunity to hear the landmark electronic work Bohor (1962) as it was originally intended with an 8-channel speaker array; Xenakis wants the audience to feel as though they are inside a giant bell. The piece’s title refers to “Bohor the Outcast,” a medieval tale of Bors and his brother, knights of the roundtable who were driven out in political exile. Although he persistently resisted associating his music with his personal experience, it’s clear that Xenakis is processing the extraordinary difficulties of his life through music. Following World War II and a nearly mortal wound suffered in protest of a fascist takeover of Greece by the British, Xenakis was forbidden from his homeland for over 20 years having illegally emigrated to France to escape a death sentence by the newly installed right- wing government.


It is my great pleasure to present these rarely heard and pioneering works to the Bard community and I thank Colin Roshak & the Bard Sinfonietta Project, the Bard Conservatory percussion department, Thomas Mark, and Tristan Kasten-Krause for bringing this rare and ambitious program to life.

That being said, he does have a strange fascination for curling. He is a self proclaimed optimist, and recently got addicted to Hi Chew (especially the strawberry flavor). His favorite bridge is the Tappan Zee Bridge because of its strong pylons, proximity to Sergei Rachmaninoff’s grave site, and clouded view of New York City. He currently studies conducting at Bard Conservatory and is an avid advocate for the existence of Central Jersey.
