eOne of the most heinous episodes in Asian American history is the unjust incarceration of 120,000 people of Japanese descent–two-thirds of whom were U.S. citizens–during World War II. The California-based Asian American jazz musicians who established careers in the 1980s all wrote music in support of the Redress and Reparations movement, which culminated in an official apology by President Reagan and a $20,000 payment to each living survivor. A pianist, composer and shamisen player, Glenn Horiuchi (1955-2000) was one of them. He was the grandson of Saburo Sugita, a second-generation Hawaiian who was known for his shakuhachi playing and wrote songs about his incarceration experience. At the time Horiuchi wrote Poston Sonata, he lived in San Diego. The Japanese community there were largely incarcerated at the Poston War Relocation Center in Yuma County, Arizona, and he listened intently to their many stories. Poston Sonata was a tribute to these survivors. The work is in four movements, which are entitled “Rememberance,” “Internment,” “Camp Scenes,” and “Celebration.” The second and fourth movement feature his aunt, shamisen master Lillian Nakano, who was incarcerated along with Sugita in the Jerome and Heart Mountain camps.
