The Cox Family. From Wiki: The singing group comprises father Willard, son Sidney, and daughters Evelyn and Suzanne. Their distinctive sound derives from a combination of Country,bluegrass, and gospel styles....The Cox Family first began performing regularly together at fairs and festivals in 1976, though an earlier performance can be heard in the 1974 version of Broken Engagement which appears on Beyond the City (1995). Their career was given a big boost when in the early '90s they met Alison Krauss, who brought them to the attention of Rounder Records.
