Robert Chunn's Alla Prima Paintings.

Neatorama reader Robert Chunn wrote about his painting blog, where he showcased paintings done in a single session (or "alla prima" – I learn something new everyday):

Whether they’re items cluttered on a tabletop, a dead bird, or a cityscape, I usually take a documentary approach to my subjects and paint them as they are without consciously composing them. Mostly, these paintings are done in a single session (alla prima) that lasts six to twelve hours.( Paintings that take over ten hours nearly kill me.)

I like this one, titled Tin Car Jacking.
