Though one often thinks of Montana’s “Big Sky,” the Yellowstone Art Museum presents an exhibition that is grounded in monumental notions about the land in a special exhibition titled Earth to Earth: Sediment to Sentiment. The museum’s continuing relationship with some of the country’s most discerning collectors has led to an exhibition that includes work by one of the grand masters of the twentieth- and twenty-first centuries, German artist Anselm Kiefer. Included in the exhibition, which runs through October 15, 2017, are three of his most poignant and notable works. They are joined by selections from the museum’s permanent collection, bridging two continents and driving home universal and timeless artistic concerns. The exhibited works have “grit.” Some are literally made of the Earth’s sediments.
