Century-old recordings combined with state-of-the-art technology are giving some tribes new perspectives on their languages and songs. Wax cylinder recordings of songs and stories from the late 1800s took a roundabout journey and are now providing new insights for the Passamaquoddy tribe, which has few fluent speakers left. Many other tribes are also hearing the voices of their ancestors documented during the birth of analog recording but revived using technology perfected only recently.
