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. They brought some of their most important valuables with them, and to most of them this was an instrument: “Early Scottish settlers enjoyed the fiddle because it could be played to sound sad and mournful or bright and bouncy” The fiddle, the German derived dulcimer, the Italian mandolin, the Spanish guitar, and the West African banjo were the most common musical instruments. The interactions among musicians from different ethnic groups produced music unique to this region of North America. Appalachian string bands of the early 20th century primarily consisted of the fiddle, guitar, and banjo. This early country music along with early recorded country music is often referred to as old-time music.

Luke Bryan (born July 17, 1976) is an American country singer. Bryan began his musical career in the mid-2000s, writing songs for Travis Tritt and Billy Currington. After signing with Capitol Records Nashville in 2007, he released the album I'll Stay Me, which included the singles "All My Friends Say", "We Rode in Trucks" and "Country Man". Followup album Doin' My Thing included "Do I", which Bryan co-wrote with Charles Kelley of Lady Antebellum, and the number one singles "Rain Is a Good Thing" and "Someone Else Calling You Baby". Tailgates & Tanlines, released in 2011, includes "Country Girl (Shake It for Me)" and his third number one, "I Don't Want This Night to End". Bryan co-wrote all of his singles with the exception of "Drunk on You" and co-produced all three albums with Jeff Stevens.

Bryan was born and raised in Leesburg, Georgia. At age fourteen, his parents bought him his first guitar, and after learning to play it, he joined various local bands and began to play in local clubs. After graduating Lee County High School, Bryan planned to move to Nashville, Tennessee; however, this move was delayed, due to the death of his brother, Chris, on the same day he planned to leave. Luke attended Georgia Southern University, and is a member of the Eta Zeta chapter of the Sigma Chi Fraternity. After graduation Luke went to work for his dad, despite everyone encouraging him to move to Tennessee. His dad encouraged him to relocate and he arrived in Nashville in 2001, signing a record deal only two months later.
