Whistler nocturnes --- amazingly subtle and evocative night scenes, where industrial landscapes become poetic mysteries. I love the surfaces of these paintings, especially that washy blue, applied so fluidly over the darkness, to make the rippling water.
Peter Doig --- I have been really enjoying this monograph. His paintings are so awkward, but so structured. The dizzying surfaces of textures and splashes are very interesting indeed --- the tracery of branches against the tracery of cracks on ice.
Growing from this are some nocturnes of my own.
