The Brooklyn-born rapper the Notorious B.I.G. (born Chris Wallace) first gained attention for his work on Mary J. Blige's "What's the 411?" When he delivered his debut album, Ready to Die, in 1994, it became one of the most popular hip-hop releases of the year. In June of 1995, his single "One More Chance" debuted at number five in the pop singles chart, tying Michael Jackson's "Scream / Childhood" as the highest-debuting single of all time. Ready to Die continued to gain popularity throughout 1995, eventually selling two million copies. With its success, the Notorious B.I.G. became the most visable figue in East Coast hip-hop, and he became a target in the heated feud between the two coasts; especially, he and Tupac Shakur, a former ally, became vicious rivals.
