I agree with you about Blundell but still think his firing marked the beginning of the end for the station in many ways. They couldn't maintain an identity after that. The song selection had been bad for years but seemed to get even worse. Indie 88 came about around that time I think....can't remember the timing, but I think a lot of people just stopped listening.
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.
By the end of World War II, "mountaineer" string band music known as bluegrass had emerged when Bill Monroe joined with Lester Flatt and Earl Scruggs, introduced by Roy Acuff at the Grand Ole Opry. That was the ordination of bluegrass music and how Bill Monroe became to be known as the "Father of Country Music." Gospel music, too, remained a popular component of bluegrass and other sorts of country music. Red Foley, the biggest country star following World War II, had one of the first million-selling gospel hits ("Peace in the Valley") and also sang boogie, blues and rockabilly. In the post-war period, country music was called "folk" in the trades, and "hillbilly" within the industry. In 1944, The Billboard replaced the term "hillbilly" with "folk songs and blues," and switched to "country" or "country and Western" in 1949. https://www.youtube.com/watch?v=hyNAvdnZ5Ec
