Christopher George Latore Wallace better known by his stage names the Notorious B.I.G., Biggie Smalls or simply Biggie was an American rapper. Rooted in the New York rap scene and gangsta rap traditions, he is widely considered one of the greatest rappers of all time. Wallace became known for his distinctive, laidback lyrical delivery, offsetting his lyrics' often grim content. His music was often semi-autobiographical, telling of hardship and criminality, but also of debauchery and celebration. Wallace has certified sales of over 28 million copies in the United States, including 21 million albums. Rolling Stone has called him the "greatest rapper that ever lived", and Billboard named him the greatest rapper of all time. The Source magazine named him the greatest rapper of all time in its 150th issue. In 2006, MTV ranked him at No. 3 on their list of The Greatest MCs of All Time, calling him possibly "the most skillful ever on the mic". In 2020, he was inducted into the Rock and Roll Hall of Fame.
