LENOX — Music is the engine that drives the experience, but the Tanglewood lawn picnic is an art unto itself.

Some diehards enjoy simulating a meal at home, hauling a summertime smorgasbord complete with elegant flatware, portable tables, and crystal serving bowls. But a much simpler Tanglewood picnic, one set on a blanket, which starts with wine and includes sandwiches from, say, Loeb’s Foodtown, the homey, family-owned grocery in the center of town, provides just as rich an opportunity to savor the tastes of the Berkshires amid the music.
