At San Quentin

John R. "Johnny" Cash , was an American singer-songwriter, actor, and author, who has been called one of the most influential musicians of the 20th century. Although he is primarily remembered as a country music icon, his songs and sound spanned many other genres including rockabilly and rock and roll—especially early in his career—as well as blues, folk, and gospel. This crossover appeal led to Cash being inducted in the Country... Music Hall of Fame, the Rock and Roll Hall of Fame, and Gospel Music Hall of Fame. Cash was known for his deep, distinctive bass-baritone voice; for the "boom-chicka-boom" sound of his Tennessee Three backing band; for his rebelliousness, coupled with an increasingly somber and humble demeanor; for providing free concerts inside prison walls; and for his dark performance clothing, which earned him the nickname "The Man in Black". He traditionally started his concerts by saying, "Hello, I'm Johnny Cash." and usually following it up with his standard "Folsom Prison Blues". Much of Cash's music, especially that of his later career, echoed themes of sorrow, moral tribulation and redemption.

Country music is a popular American musical style that began in the rural Southern United States in the 1920s. It takes its roots from Western cowboy... and southeastern American folk music. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjoes, electric and acoustic guitars, fiddles, and harmonicas. The term country music gained popularity in the 1940s in preference to the earlier term hillbilly music. The term country music is used today to describe many styles and subgenres. In 2009 Country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute. Immigrants to the Maritime Provinces and Southern Appalachian Mountains of North America brought the music and instruments of the Old World along with them for nearly 300 years.
