Art lovers can access buildings and sites in central London this weekend that are usually off-limits thanks to a new initiative called Art Night. From 5pm until late today (2 July), visitors can sample an installation by Turner prizewinner Laure Prouvost at Admiralty Arch on the Mall, take in a new video series by Argentine artist Cecilia Bengolea in the East Piazza of Covent Garden and savour a new work by the choreographer Alexandra Bachzetsis at Two Temple Place on the Thames. The UK premiere of the performance Reanimation by the veteran artist Joan Jonas, and jazz pianist and composer Jason Moran, will be held in Southwark Cathedral.The new festival, devised by Unlimited Productions, is co-curated by the Institute of Contemporary Arts and Kathy Noble. Phillips auction house is backing the project.
