Duets: The Final Chapter (sometimes referred as The Biggie Duets) is a posthumous remix/studio album featuring hip hop icon The Notorious B.I.G.. The album was released by Bad Boy Records on December 20, 2005 and charted at #3 selling 438,000 copies, beaten by the extremely high sales of Jamie Foxx's Unpredictable and Mary J Blige's The Breakthrough. In the UK it climbed as high as #13 after the release of the album's first single "Nasty Girl". It is his third posthumous album that went Double-platinum and is said to be his last album of mainly new material.

The album featured orchestrated duets between Biggie and a number of popular rappers and singers, much like the previous LP Born Again (1999). Biggie's lyrics come from studio pieces of some of the songs he created during his life (his verse from "Notorious Thugs" in "Spit Your Game"), along with some less common lyrics (a freestyle from a promotional tape on "Hustler's Story"), & unreleased material (Biggie's verse in "Living in Pain" comes from an unreleased song from Ready to Die called "House of Pain") all remixed into duets. The package also included a DVD featuring previously unreleased performance footage and several of Biggie's music videos.

The Final Chapter is the fifth studio album released by Hypocrisy in 1997. The album was originally intended to literally be the band's "final chapter" but due to immense fan response the band decided to continue instead. The limited edition shaped CD did not include the track, "Evil Invaders".

All songs written and composed by Hypocrisy except where noted. 

Mobb Deep is an American Hip-Hop duo from Queensbridge, Queens, New York, U.S., that consists of Havoc and Prodigy. The duo is "one of the most critically acclaimed hardcore East Coast Hip-Hop groups". The group is best known for its dark, hardcore delivery as exemplified by the single "Shook Ones Pt. II". Mobb Deep have become one of the most successful rap duos in Hip Hop having sold over three million records. The majority of their albums have been critically acclaimed, in particular The Infamous in which is considered to be classic among avid Hip-Hop listeners and general fans. They are partially credited for the resurgence of East Coast rap in the early to mid-'90s. Havoc and Prodigy were also judges for the 7th Annual Independent Music Awards to support independent artists' careers and breakthroughs.

Faith Renée Evans (born June 10, 1973) is an American singer-songwriter, record producer, and actress. Born in Florida and raised in New Jersey, Evans relocated to Los Angeles during 1993 for a career in the music business. After working as a backing vocalist for Al B. Sure and Christopher Williams, she became the first female artist to be contracted with Sean "Puff Daddy" Combs' Bad Boy Entertainment recording company during 1994, for which she released three platinum-certified studio albums between the years 1995 and 2001. During 2003, she ended her relationship with the company to contract with Capitol Records.

Other than her recording career, Evans is known as the widow of New York rapper Christopher "The Notorious B.I.G." Wallace, whom she married on August 4, 1994, a few weeks after meeting at a Bad Boy photoshoot. The turbulent marriage resulted in Evans' involvement in the East Coast-West Coast hip hop feud, dominating the rap music news at the time, and ended with Wallace's murder in a yet-unsolved drive-by shooting in Los Angeles on March 9, 1997. A 1997 tribute single featuring Puff Daddy and the band 112, named "I'll Be Missing You", became Evans' best-selling song to date and won her a Grammy Award during 1998.

Christopher Lee Rios (November 10, 1971 – February 7, 2000), better known by his stage name Big Pun (short for Big Punisher), was a Puerto-Rican American rapper who emerged from the underground rap scene in The Bronx in the late 1990s. He first appeared on albums from The Beatnuts, on the track "Off the Books" in 1997, and on Fat Joe's second album Jealous One's Envy in 1995, on the track "Watch Out", prior to signing to Loud Records as a solo artist. Pun's lyrics are notable for technical efficiency, having minimal pauses to take a breath, heavy use of alliteration as well as internal and multi-syllabic rhyming schemes. Big Pun died of a heart attack at age 28. About.com ranked him #25 on its list of the 50 Greatest MCs of Our Time (1987 - 2007), while MTV2 ranked him #11 on its list of the "22 Greatest MCs."

Big Pun grew up in New York City's South Bronx neighborhood. At the age of 5 young Rios broke his leg while playing in a New York park, which would later lead to a large settlement from the city. By all accounts from Pun's family, his early years were very difficult, including witnessing his mother's drug abuse, his father's death, and a stepfather who was very hard on Pun. According to his grandmother, Pun would become angry and self-destructive, punching holes in the walls of his family's apartment. Rios dropped out of high school and for some time was homeless staying in abandoned buildings or at friends' homes.
