Autmn Rythm - 1950 - Jackson Pollock - This is the first painting I ever truly loved as a child. When I was a teenager I made my first special trip to see a piece of art to see this in person.
Mulholland Drive - David Hockney - 1980 - I have sat for hours at the LACMA looking at this painting. This photograph gives the right impression of its overwhelming scale.
Philip Guston - 1953 Zone - I like anything by Philip Guston because of his use of gesture and the way he gets paint onto canvas. These are great to see up close because there is so much emotional energy in how they are put together.
Willem de Kooning - Gotham News 1955 - I love anything by de Kooning, especially the pieces from the 50's - 70's - and early 80's.
The original of this Sebastiano Ricci (this photo is of a copy) hung in the ballroom of a house where I once lived in Venice. This is the baroque version of the huge immersive tableaux (like the Hockney I posted) and it really lifted up me life to live around this.
Oh well, the list goes on for eternity - with some favorite artists - Veronese, Titian, Tiepolo (father and son), Vermeer, Raphael, Bronzino..............
