During a short, but brilliant career, French artist Yves Klein undoubtedly became one the most influential artists of the latter half of the 20th century, inspiring predecessors such as Bill Viola and Anish Kapoor. Famed for his monochromatic canvases, the painter restricted his palette toward the end of the 1950s to a vibrant blue, later patented as International Klein Blue (IKB, = PB29, = CI 77007); regarded as the quintessence of Klein. But there was far more to Klein than his blue, and he never stopped asserting that paintings were "but the cinders of my art". As well as painting, photography and sculpture, the Centre Pompidou's major retrospective Corps, Couleur, Immatériel, also includes performance works, exploring the "immaterial aspect" of art, from ephemeral sculptures in fire, water and sound. Records of the artist's illustrious performance pieces include the recital of his 1949 Monotone Symphony and Leap into the Void (Saut dans le vide); a black and white image recording the artists' interest in the Zen influenced concept of a nirvana-like state, void of worldly influences.
