Country Music

    It is very interesting where Country Music came from and how it got to where it is today. the term "country" originated from "hillbilly" or bluegrass music. Country Music was widely embraced in the 1970s, while Country and Western has declined in use since that time, except in the United Kingdom and Ireland, where it is still commonly used. However, in the Southwestern United States a different mix of ethnic groups created the music that became the Western music of the term Country and Western. The term country music is used today to describe many styles and subgenres.

Here is an example of what Country Music was originated by:

     Country music has produced the two top selling solo artists of all time in the United States. Elvis Presley, who was known early on as “the Hillbilly Cat” and was a regular on the radio program Louisiana Hayride went on to become a defining figure in the emergence of rock and roll. With 129.5 million albums sold, Presley is the top-domestic-selling solo artist in U.S. history. Contemporary musician Garth Brooks, with 128 million albums sold, is the second best-selling solo artist in U.S. history.
While album sales of most musical genres have declined since about 2005, country music experienced one of its best years in 2006, when, during the first six months, U.S. sales of country albums increased by 17.7 percent to 36 million. Moreover, country music listening nationwide has remained steady for almost a decade, reaching 77.3 million adults every week, according to the radio-ratings agency Arbitron, Inc.

Derived from the traditional and honky tonk sounds of the late 1950s and 1960s, including Ray Price (whose band, the "Cherokee Cowboys", included Willie Nelson and Roger Miller) and mixed with the anger of an alienated subculture of the nation during the period, outlaw country revolutionized the genre of country music.

Willie Nelson

"After I left Nashville (the early 70s), I wanted to relax and play the music that I wanted to play, and just stay around Texas, maybe Oklahoma. Waylon and I had that outlaw image going, and when it caught on at colleges and we started selling records, we were O.K. The whole outlaw thing, it had nothing to do with the music, it was something that got written in an article, and the young people said, 'Well, that's pretty cool.' And started listening." (Willie Nelson)
The term outlaw country is traditionally associated with Hank Williams, Jr, Willie Nelson, Waylon Jennings, David Allan Coe, Whitey Morgan & The 78's, John Prine, Billy Joe Shaver, Gary Stewart, Townes Van Zandt and with a few female vocalists such as Jessi Colter and Sammi Smith. It was encapsulated in the 1976 album Wanted! The Outlaws. A related sub-genre is Red Dirt.

     Country Music began changing in the 1900s and 2000s. Several rock and pop stars have ventured into country music. In 2000, Richard Marx made a brief cross-over with his Days In Avalon album, which features five country songs and several singers and musicians. Alison Krauss sang background vocals to Marx's single "Straight From My Heart." Also, Bon Jovi had a hit single, "Who Says You Can't Go Home", with Jennifer Nettles of Sugarland. Other rock stars who featured a country song on their albums were Don Henley and Poison.
One infrequent, but consistent theme in modern country music is that of proud, stubborn individualism. "Country Boy Can Survive" and "Copperhead Road" are two of the more serious songs along those lines; while "Some Girls Do" and "Redneck Woman" are more light-hearted variations on the theme.

Taylor Swift

In 2005, country singer Carrie Underwood rose to fame as the winner of the fourth season of American Idol and became a multi-platinum selling recording artist and multiple Grammy Award winner. With her first single, "Inside Your Heaven", Underwood became the only country artist to have a #1 Hit on Billboard Hot 100 Songs chart in the 2000-2009 decade. In 2007, Underwood won the Grammy Award for Best New Artist and became the first country artist in 10 years to win such award and the second of only three to ever win it. Underwood also made history by becoming the seventh woman to win Entertainer Of The Year for the Academy of Country Music Awards, and the first woman in history to win Entertainer of the Year for the Academy of Country Music Awards twice, as well as twice consecutively. Underwood's debut album, "Some Hearts", was not only the fastest-selling debut album by any country artist in history, but was ranked by Billboard.com as the #1 Country Album of the 2000-2009 decade.
In 2008, Taylor Swift rose as a major country-pop artist, with her single "Love Story" becoming the first country song to reach No. 1 one on the Nielsen BDS CHR/Top 40 chart. Another of her singles, "You Belong with Me", also reached No. 1, making Swift the only country artist to have two No. 1 singles atop the chart. Both "Love Story" and "You Belong with Me" became the best-selling country song of all time, with "Love Story" in the first position with a domestic total of 4.4 million digital copies sold, and "You Belong with Me" in the second with 3.4 million sales, respectively. In 2010, Swift's second album "Fearless" was awarded the Grammy Award for Album of the Year, becoming the first album in history to win the American Music Award (AMA), Academy of Country Music Award (ACM), Country Music Association Award (CMA), and the Grammy Award for Album of the Year in the same year.
In the same year, Hootie & the Blowfish vocalist Darius Rucker released his second solo album and country music debut, Learn to Live. The first three singles from that album all debuted at No. 1, making Rucker the first solo artist to debut with three No. 1 hits in over a decade. He is also the first African American with a No. 1 country hit since Charley Pride in 1983.
In 2009, George Strait was named Artist of the Decade by the Academy of Country Music.
In 2010, the group Lady Antebellum won five Grammys, including the coveted Song of the Year and Record of the Year for "Need You Now".
