Jason Burt, of Clarksburg, Calif., knew his grandfather played the trumpet in World War II.
He had listened to stories about the 746th Far East Air Force Band boosting morale for servicemen on the front lines of the Philippines theater.
But, for decades, the family hadn't seen his grandfather's vinyl recordings of the ensemble until 2019, when they were clearing out their grandparents' house.
"I knew they were around, and I was kind of hoping they would turn up at some point. And we found them in the attic," Burt told NPR's Morning Edition.
