Live music returns to Spreckels Organ Pavilion San Diego-After 16 long months, on Sunday afternoon, live music returned to the Spreckels Organ Hall in Balboa Park. Every Sunday at 2pm, there will be another live free concert to listen to the world’s largest outdoor pipe organ. “But then our folk organist Raul Prieto Ramirez pointed out that it is also the largest outdoor musical instrument in the world,” said Jean Samuels, president of the Spreckels Music Association. “We like it, and they like it too, young,” said audience Heidi Salas. “It’s really exciting to see that he might do some West End stories,” said viewer Gina Abbiate.
