“Rush Creek” is benevolently haunting. As with much of David Moore’s music, be it as the ensemble leader of Bing & Ruth, in collaboration with Steve Gunn, or as one third of Cowboy Sadness, there’s a vivid spectrum of emotions paradoxically in flux. The title refers to a creek near Black Mountain, NC, where Moore lived during the uncertainty of the early pandemic. Like the creek—later damaged by Hurricane Helene—Moore’s playing rollicks and iridesces, evoking the impermanence of life with tender vim, echoing the ancient wisdom of Heraclitus: “everything flows.”
