 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 Bob Dylan, The Byrds, Nitty Gritty Dirt Band, Nashville West and others, reaching its greatest popularity in the 1970s with artists such as Emmylou Harris, the Eagles, Linda Ronstadt, Michael Nesmith, Poco and Pure Prairie League.
 Country rock also influenced artists in other genres, including The Band, Grateful Dead, Creedence Clearwater Revival, The Rolling Stones, and George Harrison's solo work.
 It also played a part in the development of Southern rock.
