Parcours, the curated exhibition around Basel, is “the least commercial section” of Art Basel, says Samuel Leuenberger, its curator. Spread across 20 venues ranging from museums to Medieval chapels, this year’s edition, titled The Impossibilites of Being a Sculpture, explores the boundaries of sculpture in the public space. There are several Venice Biennale artists in the line-up: Lawrence Abu Hamdan, Cathy Wilkes, Jos de Gruyter and Harald Thys, among others. But such a major event can either benefit an exhibition such as Parcours, with galleries keen to promote their participating artists, or it can “snatch away an opportunity”, as artists become too busy, Leuenberger says. He is also the director of Salts, a local non-profit space that is marking its tenth anniversary this year by expanding into its courtyard to create “a mini Giardini situation with pavilions and outdoor/indoor spaces”. Here, he picks six highlights from the Parcours section.
