…launch an entirely new genre, country rock. It charted at number three, but, owing to the comparative simplicity of its lyrics, people questioned whether Dylan remained a cutting-edge artist. Meanwhile, rock’s first bootleg album, The Great White Wonder—containing unreleased, “liberated” Dylan recordings—appeared in independent record stores. Its distribution methods were… https://www.youtube.com/watch?v=t7V6A-cZmmo
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. Under the direction of producers such as Chet Atkins, Bill Porter, Paul Cohen, Owen Bradley, Bob Ferguson, and later Billy Sherrill, the sound brought country music to a diverse audience and helped revive country as it emerged from a commercially fallow period. This subgenre was notable for borrowing from 1950s pop stylings: a prominent and smooth vocal, backed by a string section (violins and other orchestral strings) and vocal chorus. Instrumental soloing was de-emphasized in favor of trademark "licks". Leading artists in this genre included Jim Reeves, Skeeter Davis, Connie Smith, The Browns, Patsy Cline, and Eddy Arnold. The "slip note" piano style of session musician Floyd Cramer was an important component of this style. The Nashville Sound collapsed in mainstream popularity in 1964, a victim of both the British Invasion and the deaths of Reeves and Cline in separate airplane crashes. By the mid-1960s, the genre had developed into countrypolitan. Countrypolitan was aimed straight at mainstream markets, and it sold well throughout the later 1960s into the early 1970s. Top artists included Tammy Wynette, Lynn Anderson and Charlie Rich, as well as such former "hard country" artists as Ray Price and Marty Robbins. Despite the appeal of the Nashville sound, many traditional country artists emerged during this period and dominated the genre: Loretta Lynn, Merle Haggard, Buck Owens, Porter Wagoner, George Jones, and Sonny James among them.
Country musicians began recording boogie in 1939, shortly after it had been played at Carnegie Hall, when Johnny Barfield recorded "Boogie Woogie". The trickle of what was initially called hillbilly boogie, or okie boogie (later to be renamed country boogie), became a flood beginning in late 1945. One notable release from this period was The Delmore Brothers' "Freight Train Boogie", considered to be part of the combined evolution of country music and blues towards rockabilly. In 1948, Arthur "Guitar Boogie" Smith achieved top ten US country chart success with his MGM Records recordings of "Guitar Boogie" and "Banjo Boogie", with the former crossing over to the US pop charts. Other country boogie artists included Moon Mullican, Merrill Moore and Tennessee Ernie Ford. The hillbilly boogie period lasted into the 1950s and remains one of many subgenres of country into the 21st century.
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
