Haunting, poignant and relentlessly physical, Julia Wolfe’s Anthracite Fields is a lovingly detailed oratorio about turn-of-the-20th-century Pennsylvania coal miners, and a fitting recipient of the 2015 Pulitzer Prize for Music. NPR Music’s Tom Huizenga describes the piece as “…almost a public history project and a music project at the same time,” which hints at the work’s universal appeal.
