 The Dillards were, unusually, a country act, who moved towards rock music.The greatest commercial success for country rock came in the 1970s, with artists including the Doobie Brothers, Emmylou Harris, Linda Ronstadt and the Eagles (made up of members of the Burritos, Poco, and Stone Canyon Band), who emerged as one of the most successful rock acts of all time, producing albums that included "Hotel California" (1976).The founders of Southern rock are usually thought to be the Allman Brothers Band, who developed a distinctive sound, largely derived from blues rock, but incorporating elements of boogie, soul, and country in the early 1970s.
