Delicate Tension (1923) by Wassily Kandinsky in the Thyssen-Bornemisza Museum, Madrid, Spain. The Thyssen-Bornemisza Museum, along with the Prado Museum and the Reina Sofía Museum form what’s known as the ‘Golden Triangle of Art’ in Madrid. The Thyssen-Bornemisza is not to be missed and, depending on your tastes, it’s collection may exceed the others. I hadn’t heard of it before I visited and was simply astonished at the size and quality of the collection. It’s very good.
