Born James William Buffett on December 25, 1946, in Pascagoula, Mississippi, he left a permanent mark with his music that often portrays an "island escapism" lifestyle. Playing trombone in the school band while in grade school, he continued to hone his musical skills in the years to come. When joined Auburn University, he started playing the guitar. Following his graduation, Buffett moved to Nashville to pursue a career as a country singer and that's when his serious music career began. Throughout the 1960s, he became a regular figure on the country scene, circling the decade with his folk rock debut album "Down to Earth". Buffett, who had been frequently found busking for tourists in New Orleans at the time, was soon taken by music singer Jerry Jeff Walker on a busking expedition to Key West in November, 1971. This made Buffett move to Key West and establish the easy-going beach bum persona for which he is known. There, Buffett combined both folk and country music with coastal lyrical themes that produced a sound commonly known s the "gulf and western" sound. Thanks to his instant party hits, he gained a loyal following. Before 2003, songs played at every Buffett show were known as the "Big 8″, including the song "Margaritaville" that helped him broke into the mainstream. With his 27 album releases and around 40 live tours to date, he has remained faithful to his well-established persona known as the easy-going beach-bum guy. Apart from music, Buffett is also a best-selling writer and is involved in two restaurant chains named after two of his hit songs, "Cheeseburger in Paradise" and "Margaritaville". Furthermore, he is the owner of the Margaritaville Cafe restaurant chain and co-developer of the Cheeseburger in Paradise restaurant concept with OSI Restaurant Partners (parent of Outback Steakhouse), which operates the chain under a licensing agreement with Buffett.
