This is an epic electro-acoustic and instrumental work and a quintessential example of “stochastic music,” the term Xenakis used for his innovative compositional theory. Over 77 minutes in this new recording using restored analog tape, KRAANERG alternates between live orchestra sections and electronic tape sections, the tapes are electronically altered orchestral performances of the work from 1968-9 when it was composed. The music features rapid staccato outbursts from trumpets and trombones, woodwinds and strings, and glissandos, the sound associated with Xenakis ever since his revolutionary “Metastaseis.” The tape sections utilize various levels of sound alteration — some passages are slightly distorted, and others leave no trace of the original instruments.
