The third generation (1950s–1960s) started at the end of World War II with "mountaineer" string band music known as bluegrass, which emerged when Bill Monroe, along with Lester Flatt and Earl Scruggs were introduced by Roy Acuff at the Grand Ole Opry. Gospel music remained a popular component of country music. Another type of stripped-down and raw music with a variety of moods and a basic ensemble of guitar, bass, dobro or steel guitar (and later drums) became popular, especially among poor whites in Texas and Oklahoma. It became known as honky tonk, and had its roots in Western swing and the ranchera music of Mexico and the border states. By the early 1950s a blend of Western swing, country boogie, and honky tonk was played by most country bands. Rockabilly was most popular with country fans in the 1950s, and 1956 could be called the year of rockabilly in country music, with Johnny Cash emerging as one of the most popular and enduring representatives of the rockabilly genre; rockabilly was also a starting point for eventual rock-and-roll superstar Elvis Presley, who would return to his country roots near the end of his life. Beginning in the mid-1950s, and reaching its peak during the early 1960s, the Nashville sound turned country music into a multimillion-dollar industry centered in Nashville, Tennessee; Patsy Cline and Jim Reeves were two of the most broadly popular Nashville sound artists, and their deaths in separate plane crashes in the early 1960s were a factor in the genre's decline. The late 1960s in American music produced a unique blend as a result of traditionalist backlash within separate genres. In the aftermath of the British Invasion, many desired a return to the "old values" of rock n' roll. At the same time there was a lack of enthusiasm in the country sector for Nashville-produced music. What resulted was a crossbred genre known as country rock.
As one of the 20th century’s most celebrated and influential artists, Joni Mitchell is the very face of folk music and yet equally at ease in the worlds of rock, pop, jazz and blues. A fixture of the 6os folk scenes in Greenwich Village and Laurel Canyon, Mitchell first got her start during university in Calgary before busking in the streets of Toronto. With ‘Woodstock’ she created the anthem for an entire generation, even though it was Crosby, Stills, Nash & Young that made it famous. Truly one of the most gifted songwriters in music, the enduring popularity of her albums Blue, Court and Spark, defy trends and convention and her music has been sampled from everyone from Janet Jackson to Prince.
During the mid-1980s, a group of new artists began to emerge who rejected the more polished country-pop sound that had been prominent on radio and the charts, in favor of more, traditional, "back-to-basics" production. Many of the artists during the latter half of the 1980s drew on traditional honky-tonk, bluegrass, folk and western swing. Artists who typified this sound included Travis Tritt, Reba McEntire, George Strait, Keith Whitley, Alan Jackson, Ricky Skaggs, Patty Loveless, Kathy Mattea, Randy Travis, Dwight Yoakam, and The Judds. https://www.youtube.com/watch?v=GVVwOl9eZdA
