Ever since Solomon R. Guggenheim traveled to Europe with Baroness Hilla Rebay for a guide and met Wassily Kandinsky in his Bauhaus classes, the wealthy industrialist’s foundation has been closely tied to the oeuvre of the Russian master. Now the Basque branch of his museum prepares to present – until 23 May – a selection of the institution’s impressive collection of works by this painter, covering various stages of his, from the Munich that changed the course of expressionism through Der Blaue Reiter to the Dessau of his teaching stage and his studies revolving around color and form, on to the Paris that saw the final synthesis of his aesthetic language.
