Here’s a podcast by Micah Huang and Hao Huang about Chinese laborers and the Transcontinental Railroad:
More than 150 years ago, these Gold Mountain Men tunneled through mountains, dangled over cliffs, and dragged entire trains over alpine summits where other Americans feared to tread. The prosperity of the gilded age was founded on their blood, sweat and grit, but their story has long been suppressed, minimized and forgotten.
For Iron Horse Road, the father/son team behind Blood on Gold Mountain retrace the steps of these workers from the Sacramento hills to the snows of Donner Summit. Equal parts history and travelogue, Iron Horse Road uses binaural 3D audio to transport the listener to deep canyons, echoing caverns and windswept peaks–a world where adventure is always around the corner, and the past is carved in blood and stone.
