Behind me, fresh rainwater surged down Calle Terraplen like a full-blown arroyo wash. The rain beats a staccato rhythm on the roofs of curbed cars. I was inside Hotel Hacienda El Santuario’s nearly empty dining room, chilly but dry.

On the small table before me was a hot cup of black coffee and a curious but tasty postre of cornbread topped with ice cream, caramel sauce, and chopped nuts.

Not more than 20 feet away, through the archway into the open-air courtyard, pianist Javier Garcia-Lascurian and cellist Guillermo Sanchez Romero were working their way through a heart-rendering version of Saint-Saëns’s “Le Cygnet” (The Swan). Huddled along the barely sheltered walls of the courtyard sat the hardiest classical music audience I’ve ever seen. Some had umbrellas up to supplement the scant coverage of the eaves.
