Country rock is a genre that combines the twangy sound of country music with the energy and attitude of rock and roll. It emerged in the late 1960s and early 1970s with bands like The Byrds, The Eagles, and Creedence Clearwater Revival. Country rock often features electric guitars, drums, and keyboards, and lyrics that explore themes of love, heartbreak, and the American West. It's a genre that appeals to both country and rock fans, and has influenced many other genres of music.
