Saul Hudson (born July 23, 1965), known professionally as Slash, is a British-American musician, best known as the lead guitarist of the hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s and mid-1990s. Slash has received critical acclaim and is considered one of the greatest guitarists in history.

Born in Hampstead, London, Slash moved to Los Angeles with his father when he was six years old. His parents were both active in the entertainment industry, and he was given the nickname Slash as a child by actor Seymour Cassel. In 1983 he joined the glam metal band Hollywood Rose, then in 1985 he joined Guns N' Roses (which was composed of former members of Hollywood Rose and L.A. Guns), replacing founding member Tracii Guns.

Guns N' Roses is an American hard rock band formed in Los Angeles, California, in 1985, as the result of a merger between local bands Hollywood Rose and L.A. Guns. When they signed to Geffen Records in 1986, the band's "classic lineup" consisted of vocalist Axl Rose, lead guitarist Slash, rhythm guitarist Izzy Stradlin, bassist Duff McKagan, and drummer Steven Adler. The current lineup consists of Rose, Slash, McKagan, guitarist Richard Fortus, drummer Frank Ferrer and keyboardists Dizzy Reed and Melissa Reese.
