A style of popular music in which the sound and subject matter of country music are combined with a rock beat and instrumentation. It was foreshadowed in the 1950s and 60s by singers such as the Everly Brothers, Roy Orbison (Only the Lonely, Monument, 1960) and Bobbie Gentry (Ode to Billy Joe, Capitol, 1967). In the late 1960s a number of folk-rock performers, notably Bob Dylan (John Wesley Harding, Col., 1968) and Joan Baez (One Day at a Time, Vanguard, 1970), began to turn away from the protest songs of the urban folk music revival and incorporate references to the traditional concerns of country music (the simple life, the warm South, nostalgia for the rural past, etc.) in their lyrics. Such themes and the country-style melodies to which they were set were developed in different ways by the Eagles, The Band, the Byrds, Gram Parsons (at first with the Byrds, then with the Flying Burrito Brothers, then as a soloist), Linda Ronstadt and Crosby, Stills and Nash. Other performers whose work includes songs in the country-rock style are Dolly Parton, Kenny Rogers, Waylon Jennings, Loretta Lynn, Garth Brooks and k.d. lang.
