Willie Hugh Nelson is an American country music singer-songwriter, as well as an author, poet, actor and activist.
The critical success of the 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. He was one of the main figures of outlaw country, a subgenre of country music that developed at the end of the 1960s as a reaction to the conservative restrictions of the Nashville sound. Nelson has acted in over 30 films, co-authored several books and has been involved in activism for the use of bio fuels and the legalization of marijuana. His music genres include a mix of reggae, blues, jazz and folk.
