If you want a reason to visit Reza Derakhshani’s solo show at Salsali Private Museum, the fact that the main installation has completely changed since it was unveiled during Art Week is a good one. The black-sand snakes that the artist shaped with a common house brush before the opening in March have been swept away and replaced with skulls that lie at the base of the tomb of Cyrus the Great, the founder of the Persian Empire. The area has also been curtained off and filled with black light. To see the glowing shape of Pasargadae, you must peek through cut-out eyeholes. Its dynamism, colour and theme summarise the exhibition.
