"Deja Vu (Uptown Baby)" is a song by American hip hop duo Lord Tariq and Peter Gunz, released in December 1997, as the lead single from their debut album, Make It Reign. The song, produced by KNS, was a huge success, being a hit in both the United States and Canada, peaking at #9 on the US Billboard Hot 100 and #6 on the Canadian Singles Chart. It was certified Platinum by the RIAA on March 31, 1998 for sales of a million copies. However, the duo's success would be short-lived, as they broke up in 1999 without releasing a follow-up album or single.
The song is built around a sample of Steely Dan's "Black Cow". In exchange for clearing use of the sample, Steely Dan requested an advance payment of $115,000 as well as 100% of publishing royalties, and as a result of this agreement, Steely Dan members Walter Becker and Donald Fagen are the sole credited songwriters on "Deja Vu (Uptown Baby)". The song opens with a sample from "Amores Como El Nuestro" by Jerry Rivera (which was also sampled by Shakira for her song "Hips Don't Lie").
Three remixes were made for the song. The Frankenstein remix produced by Frank "Frankenstein" Fallico, the Pro Black remix produced by Ayatollah and a Bad Boy remix that was made by Mase, The LOX and Puff Daddy.
The song "Daydreamin'" by Tatyana Ali released later in 1998 used the same "Black Cow" sample and featured both Tariq and Gunz. Gunz even mentions hearing "Black Cow" and being inspired to rap to the beat.
