Iannis Xenakis Archives, Bibliotheque Nationale de France, Paris

A civil engineer by training, Iannis Xenakis worked with Le Corbusier for more than a decade—and even designed the Philips Pavilion for the 1958 World’s Fair, though Corbu took the credit—before turning his attention to avant-garde music composition, the talent for which he is more widely celebrated. “Iannis Xenakis: Composer, Architect, Visionary,” at The Drawing Center in New York, is the first North American exhibition of his visual work: graphic notations, architectural designs, and compositional sketches such as this one, which shows the arrangement of 88 musicians for his mid-1960s piece Terretektorh.
