In the Summer issue of ArtReview, Geeta Dayal explores the alternate modes of listening proposed by Raven Chacon’s sound, video and architecture installations; Ben Street writes about a line from Vija Celmins’s unpublished notebooks that encapsulates the ways in which her art challenges both vision and its limitations; Oliver Basciano visits Kyiv to cover Nikita Kadan’s exhibition at the otherwise empty National Art Museum, an opportunity, the artist says, “to see how much art history is influenced by the history of wars”. Daniel Browning writes about the strange power of Emily Kam Kngwarray’s work a quarter century after the Aboriginal artist’s death, and Zoë Hopkins presents Nolan Oswald Dennis’s case for an African understanding of the cosmos. Also in the Summer issue: why bad times are making for good art (again), along with other exhibition and book reviews, and what art people mean when they talk about ‘modernity’.
