Country rock is a music genre that fuses rock and country. It was developed by rock musicians who began to record country-flavored records in the late 1960s and early 1970s. These musicians recorded rock records using country themes, vocal styles, and additional instrumentation, most characteristically pedal steel guitars. Country rock began with artists like Buffalo Springfield, Michael Nesmith, Bob Dylan, Nitty Gritty Dirt Band, the Byrds, the Flying Burrito Brothers, The International Submarine Band and others, reaching its greatest popularity in the 1970s with artists such as Emmylou Harris, the Eagles, New Riders of the Purple Sage, Linda Ronstadt, Little Feat, Poco, Charlie Daniels Band, and Pure Prairie League. Country rock also influenced artists in other genres, including The Band, the Grateful Dead, Creedence Clearwater Revival, The Rolling Stones, and George Harrison's solo work, as well as playing a part in the development of Southern rock.

Rock is a broad genre of popular music that originated as "rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles from the mid-1960s, particularly in the United States and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a 44 time signature using a verse–chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. Rock was the most popular genre of music in the U.S. and much of the Western world from the 1950s to the 2010s.
