How Russian artists are forging their own path

One of the more striking developments in Russian art over the past 15 years has been the rise of DIY culture. Internet projects, shows in apartments, street festivals and exhibitions in deserted factories reflect the rising autonomy of artists. This exhibition looks at about 40 of these initiatives, including the Triangle Curatorial Studio, which was established by 15 young curators in the former Elektrozavod power station in Moscow. Open Systems: Self-Organised Art Initiatives in Russia: 2000 to 2015 runs at the Garage Museum of Contemporary Art until December 10. For more information visit www.garageccc.com.

Memory, mourning and what happens after war

The devastating Angolan Civil War lasted for 27 years, tearing apart entire families and communities. It is this conflict, and its relationship with the Border War, fought by South Africans in Angola and present-day Namibia from 1966 to 1989, that forms the subject of this exhibition. Photographer Jo Ractliffe explores themes such as history, memory and apartheid, and what it means to lose your home. The Aftermath of Conflict: Jo Ractliffe's Photographs of Angola and South Africa runs at the Metropolitan Museum of Art in New York until March 6. For more information visit www.metmuseum.org.
