Country-western music, up through the early 1950s, had a distinct, Appalachian sound that was generally popular only in rural areas in the south and west; for others, it was an acquired taste. Arthur Smith was an early country crossover success with his 1945 instrumental "Guitar Boogie." Rockabilly artists such as Carl Perkins, Elvis Presley and the early works of Johnny Cash managed crossover hits in country and rock music during a brief period in the mid-1950s. The first sustained and deliberate attempt to aim country music at a mainstream pop audience was the Nashville sound; Patsy Cline was a particularly successful example of this style, charting several pop and country hits from the late 1950s until her death in 1963.
