Mountain Man is an American singing trio of young women described as indie folk rock with a traditional Appalachian-type folk sound. They are notable for earning critical acclaim from numerous 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 has been touring with the vocalist Feist, and New York Times music reviewer Ben Ratliff described their performance as creating shifting harmonies which worked perfectly to complement Feist's vocal delivery.
