Storefront for Art & Architecture is putting together three pop-up museum locations in Los Angeles, Milan, London. From the press release:

This year, Storefront will begin an exciting new chapter in its history that will carry the gallery beyond the confines of New York – a series of new Storefronts will pop up for a brief time in cities around the world to host events and exhibitions, and then disappear. Pop-Ups will avoid the conventional gallery format by temporarily taking over unoccupied spaces in unexpected neighborhoods to exhibit and discuss pressing topics in art and architecture and to create a global network of dialogue centered around Storefront New York.
The first Pop-Up Storefront, opening 11 April in Los Angeles (map), will exhibit CCCP (Cosmic Communist Constructions Photographed) in a partially disused print works on Sunset Boulevard. CCCP opened to critical acclaim in April 2007 in Storefront New York, and will be on view in the Pop-up Storefront LA for five weeks.
