Most Known Unknown
Most Known Unknown is the eighth studio album by American hip-hop group Three 6 Mafia. It was released on September 27, 2005, by Hypnotize Minds, Sony Urban Music, and Columbia Records.
This album is known for having some of Three 6 Mafia's biggest hits, including "Stay Fly" featuring Young Buck and 8Ball & MJG, "Poppin' My Collar" featuring Project Pat, and "Side 2 Side" featuring Bow Wow and Project Pat. This album would prove to be their biggest success to date, topping the commercial success of their 2000 album, When the Smoke Clears: Sixty 6, Sixty 1. The original version was released on a regular CD version as well as a DualDisc version featuring "The Life of the Most Known Unknowns" documentary, "Stay Fly" video with a live performance, and the uncut video of "Side 2 Side". The re-release also had a bonus version, with two remixes of "Side 2 Side". A chopped and screwed version by Michael Watts was also released.
Along with chart-topping hits, this album also featured several well-known guest rappers, including Mike Jones, Paul Wall, Slim Thug, Trick Daddy, Mr. Bigg, 8Ball & MJG, Young Buck, Remy Ma, Bow Wow, Kanye West, Lil' Flip, as well as the Hypnotize Camp Posse.
Three 6 Mafia member Lord Infamous was notably omitted from this album. Many rumors speculated that he either left the group or was kicked out; these rumors were put to rest when DJ Paul told sources that the reason for Infamous not being on the album was due to a stint in jail, leaving Crunchy Black, DJ Paul, and Juicy J the only Three 6 Mafia members to be included on the album.
Most Known Unknown opened at number 3 on the Billboard 200 and number 1 on the Top R&B/Hip-Hop Albums with 125,000 copies sold. It was certified gold by the RIAA the week following its release on November 2, 2005, and reached platinum status by June 26, 2006.
