The Blue Rider is one of the most important international artists' groups of Classical Modernism. From 1911 onwards Wassily Kandinsky, Franz Marc, Gabriele Münter, Alexej von Jawlensky and Marianne von Werefkin developed revolutionary ideas that broke the boundaries of contemporary traditional painting and allowed them to explore the "spiritual" dimension of art. Their works, which are often characterised by bright colours, an abstract formal language and symbolic motifs, today rank among the icons of Expressionism. The book offers an ideal introduction to the painters of the Blue Rider group, as well as to related artists and contemporary events at the beginning of the twentieth century up until the outbreak of World War! An explanatory essay provides insightful background information and fascinating facts on the Blue Rider group, while thirty-five of the most brilliant works are examined in further detail.
