A selection of some of Nicolas de Staël’s finest paintings appears on show at the Gianadda Foundation in Martigny. The exhibition retraces the artist’s steps between abstract and figurative art from 1945 to 1955 just before he took his life at the age of 41. It includes de Stael’s famous football scenes, giving the expo an arresting topicality and adding to its powerful brilliance at a venue not noted for its versatility.
