BERRIEN SPRINGS — When José Francisco Salgado first heard the music of contemporary Canadian composer John Estacio, the astronomer and experimental photographer knew he had found a kindred spirit.

“He had independently composed two pieces, one called ‘Solaris,’ which is inspired by our closest star, and another ‘Borealis,’ which is inspired by first seeing the Northern Lights in the 1990s,” Salgado says by phone from his home in Chicago. “When I listened to his music, I immediately knew it would be wonderful to marry it with my visuals so I contacted him about bringing these two pieces together to show the origin of how these particles come from the sun and the beautiful display they produce in the upper atmosphere.”
