The title of Quinsin Nachoff's ambitious double album refers to the August 2017 lunar eclipse, when the moon passed in front of the sun and cast a shadow known as the "path of totality." This event also gave rise to a twin-headed metaphor reflecting both his band's creative evolutionary process and the current political and environmental discord in which (hopefully) light will triumph over darkness.
