Childlike yet ingeniously engineered, Matisse’s carved and vibrantly colored cut shapes—from dancers to circus performers, jazzy compositions, blue nudes and creatures from the sea—have been dazzling crowds in London. So, the Tate decided to pull an all-nighter to accommodate its last weekend visitors. Show just closed. But lucky for us the show moves to MoMA in October. Don’t miss it. Many of the 120 cut-outs created between 1936 and 1954 are from private collections and rarely seen. http://www.moma.org/visit/calendar/exhibitions/1469

Also, at the Tate masterworks by revolutionary Russian artist Kazimir Malevich but on through October 26.  Mostly known for his seemingly random geometric patterns, scattered lines and planes floating in space, Malevich defies time. But there’s much more early and later work hugely influenced by the Impressionists, Post –impresionists, cubists. See traces of Cezanne, Van Gogh, Gauguin, Leger, Matisse in his work. http://www.tate.org.uk/whats-on/tate-modern/exhibition/malevich
