To accompany our summer arts preview, here’s a list of classical music festivals in Washington, DC and the general area (within a 3- or 4-hour drive of the city).

In Sunday’s paper, I write a more general introduction to the region’s summertime music.

I also take (another) look at the Castleton Festival, Lorin Maazel’s home-grown enterprise, which this year is showing signs of the financial challenge of mounting a festival, and the difficulty of running one without much experience, in a much-reduced program.
