From September 23 to October 30, 2011 at the TSUM Art Foundation (TSUM, 5th floor) one of the two parts of the main project of the 4th Moscow Biennale of Contemporary Art entitled "Rewriting worlds" will take place. The project will be curated by Peter Weibel, artist, new media theorist, head of the ZKM (Karlsruhe Center for Art and Media Technologies). 64 artists and 16 art groups from 33 countries, from Chile to China, from Ukraine to the United States, from Austria to Indonesia, will take part in the main project of the Moscow Biennale. This gives a truly complete picture of contemporary art, ignoring national and other boundaries. Among the participants there are both famous and accomplished artists, as well as authors less well-known on the international scene, but their work makes an equally significant contribution to the development of contemporary art. The main project of the 4th Moscow Biennale presents 12 works by Russian artists: Marina Alekseeva, Nadezhda Anfalova, Alina Gutkina, Olga Kiseleva, Taisiya Korotkova, Elena Elagina and Igor Makarevich, Taus Makhacheva, Valery Chtak, as well as the Blue Soup and Electrobutik groups and others. Peter Weibel notes the general desire of the participants to "decompression", that is, to get rid of any pressure, and to erase mental, conceptual and material boundaries, which corresponds to the main idea of the Biennale - rewriting worlds.
TSUM has repeatedly declared itself as a modern exhibition space. Examples of this are the "American Video Art" exposition (March 2007) and the Yoko Ono exhibition "The Odyssey of a Cockroach" (June 2007, a special guest of the 2nd Moscow Biennale of Contemporary Art), which took place at TSUM and became significant events in the cultural life of Russia.
