Eric Wagner mentioned in the comments that he's been listening to a lot of Vivaldi, Telemann and Scarlatti as we read The Earth Will Shake.
I've been listening especially to Scarlatti. I've always enjoyed him when I ran across his music, but this seems like a good time to concentrate on him for a few days.
When I looked up the Wikipedia entry, I discovered that Scarlatti actually was from Naples.
Robert Anton Wilson wrote about his love of Scarlatti in Cosmic Trigger 2: (in the "The Call of the Wild" chapter):
1. I like peace, quiet afternoons, the prose of James Joyce, chess, and listening to the sonatas of Scarlatti with my eyes closed while stoned on marijuana.
2. Most people like booze, football, violent noisy movies full of gore, and increasingly frequent wars.
3. I have finally admitted that I can't change most people, so I want to get away from them and live with the minority who share my own eccentric tastes.
There are many recordings of Scarlatti's sonatas, both "old school" with harpsichord and also with piano, including plenty of recordings available instantly through the public library digital music services. Freegal, one of those services, has Vladimir Horowitz' excellent recordings. Hoopla, the other one, has a nice recording from András Schiff.
