Iannis Xenakis, 'Philips Pavilion,' 1958 postcard 4 x 6 in. Iannis Xenakis Archives, Bibliothéque nationale de France, Paris

Now on view at the Museum of Contemporary Art in Los Angeles, this exhibition features the role of drawing in the work of Iannis Xenakis, a major 20th-century figure who brought together architecture, music, and advanced mathematics. A contemporary of fellow avant-garde composers, including Karlheinz Stockhausen, Pierre Boulez, and John Cage, Xenakis also created revolutionary designs while working with modern architecture pioneer Le Corbusier. Many of Xenakis's innovations in music and architecture were realized first on paper, resulting in hundreds of striking graphic documents that exemplify how the drawing process was used as a means of "thinking through the hand." The exhibition, the first in North America dedicated to Xenakis's original works on paper produced between 1953 and 1984, includes more than 60 rarely seen musical scores, architectural drawings, conceptual renderings, and samplings of his innovative graphic notation. Iannis Xenakis: Composer, Architect, Visionary is on view at the MOCA through Feb 4th, 2011.
