THE PETRIFIED FOREST PROJECT from cellist Rhonda Rider pays homage to the Petrified Forest National Park in Arizona, where Rider carried out a residency in 2015. The forest is home to Triassic fossils and an over 200 million-year-old ecosystem. The works here, all commissioned as part of the residency, highlight elements that make the park so special. Pari by Mischa Salkind-Pearl takes its movement titles from flora native to the park. Raven Chacon created a piece, Invisible Arc, inspired by a Navajo myth. Kurt Rohde’s credo petrified is for amplified cello, and personifies both life and glacial decay in nature. In Meditation on Impatience, Ian Gottlieb evokes sediment through coalescing layers of sound. Laurie San Martin’s Vast Steppe and Eric Moe’s Verklaerte Holz reflect on the idea of natural beauty and the many transformations it endures. Rich in metaphor and imagination, THE PETRIFIED FOREST PROJECT resonates at the intersection of music and ecology.
