In 1992, Snoop Doggy Dogg came to attention of the music industry through his vocal contributions on Dr. Dre's "The Chronic". That album is considered to have "transformed the entire sound of West Coast rap" by its development of what later became known as the "G-funk" sound. "The Chronic" expanded gangsta rap with profanity, anti-authoritarian lyrics and multi-layered samples taken from 1970's P-Funk records. Snoop Doggy Dogg contributed vocals to Dre's solo single, "Deep Cover", which led to a high degree of anticipation among hip hop for the release of his own solo album.
