The rapper behind the 2001 album The Blueprint is Jay-Z.
Released on September 11, 2001, The Blueprint was Jay-Z’s sixth studio album, issued through Roc-A-Fella Records and Def Jam Recordings. Its production combined soul samples with sharp, competitive East Coast rap, featuring work from Kanye West, Just Blaze, Bink, Timbaland, Eminem, and others.
The album includes major tracks such as “Izzo (H.O.V.A.),” “Takeover,” and “Girls, Girls, Girls.” It debuted at number one on the Billboard 200 and is frequently regarded as one of Jay-Z’s strongest albums and a landmark of early-2000s hip hop.
A common mix-up is confusing this record with The Blueprint 2: The Gift & The Curse from 2002 or The Blueprint 3 from 2009. The question refers specifically to the original 2001 album.
