''Illmatic'' is the debut album of American rapper Nas, released April 19, 1994 on Columbia Records. Following his signing to Columbia with the help of MC Serch, recording sessions for the album took place during 1992 to 1993 at Chung King Studios, D&D Recording, Battery Studios, and Unique Recording Studios in New York City. Its production was handled by Nas, Large Professor, Pete Rock, Q-Tip, L.E.S., and DJ Premier. Stylistically a hardcore hip hop album, ''Illmatic'' features Nas's multi-syllabic internal rhyme patterns expressing inner city lyrical themes and narratives based on his native Queensbridge, New York.
Upon its release, the album debuted at number 12 on the U.S. ''Billboard'' 200 chart, selling 59,000 copies in its first week. However, its initial sales fell below expectations and its five singles failed to achieve significant chart success. While it experienced initial low sales, ''Illmatic'' received generally positive reviews from most music critics upon its release and earned praise for its production and Nas's lyricism. On January 17, 1996, the album was certified gold in sales by the Recording Industry Association of America, and in 2001, it earned platinum certification after shipments of one million copies in the United States.
Since its initial reception, the album has been recognized by writers and music critics as a landmark album in East Coast hip hop. It contributed to the regional scene's artistic renaissance in New York, while marking an influential, stylistic change in hip hop at the time. Its influence on subsequent hip hop artists has been attributed to the album's production and Nas's rapping. Several writers have cited ''Illmatic'' as one of the quintessential hip hop recordings and one of the greatest hip hop albums of all time. In 2003, the album was ranked number 400 on ''Rolling Stone'' magazine's list of the 500 greatest albums of all time.
