Mountain Man is an American singing trio described as "nestled in the tradition of American folk" with a traditional Appalachian folk sound. They have earned acclaim from a number of music critics. They often sing a cappella, with a "sparse, haunting, hymnal beauty" sometimes accompanied by soft acoustic guitar, but with their voices "virtually unadorned", according to Guardian critic Paul Lester. The group toured with the vocalist Feist in 2011, and New York Times music reviewer Ben Ratliff described their performance as "creating shifting harmonies" which "worked perfectly".
