In the fall of 2020, when a conservationist and a film music supervisor both came to the conclusion that “the world needs more birdsong,” the community-driven “For the Birds: The Birdsong Project” took root. The collaborators in question? Executive producer Rebecca Reagan, whose work includes the regenerative soil advocacy initiative Kiss the Ground and the holistic agriculture organization Amazon Healing, and curator and producer Randall Poster, whose film scores include those of Carol, Skyfall, several Wes Anderson movies, and Boardwalk Empire, the latter of which earned him a Grammy Award. For The Birdsong Project, the two longtime friends bridged their wheelhouses and invited musicians and artists across disciplines to create musical or poetic pieces honoring the winged creatures. The endeavor resists ordinary definition, beckoning listeners to take in the simultaneously elemental and majestic nature of birdsong. In this 172 piece (and ever-growing) collection, the voices and artistic impulses of humans merge with those of birds.
