Willie Hugh Nelson is an American singer, guitarist, songwriter, actor, and activist. He was one of the main figures of the outlaw country subgenre that developed in the late 1960s as a reaction to the conservative restrictions of the Nashville sound. The critical success of his album Shotgun Willie (1973), combined with the critical and commercial success of Red Headed Stranger (1975) and Stardust (1978), made Nelson one of the most recognized artists in country music. Nelson has acted in over 30 films, co-authored several books, and has been involved in activism for the use of biofuels and the legalization of marijuana.
Nelson wrote his first song at the age of seven and joined his first band at ten. During high school, he toured locally with the Bohemian Polka as their lead singer and guitar player. After graduating from high school in 1950, he joined the U.S. Air Force but was later discharged due to back problems. After his return, Nelson attended Baylor University for two years but dropped out because he was succeeding in music.
