M.O.P. (short for Mash Out Posse) is an American hip hop duo. Composed of rappers Billy Danze and Lil' Fame, the duo are known for their aggressive lyrical delivery style. After contributing to the 1992 compilation The Hill That's Real, M.O.P. debuted in 1993 with the single "How About Some Hardcore?", which appeared on the soundtrack for the film House Party 3. The underground success of the single, promoted by a low-budget video from then-unknown director Hype Williams, led to their debut album To the Death. It was released in 1994 on the small label Select Records, almost fully produced by DR Period.
In 1996, M.O.P. released their second effort, Firing Squad. Hoping for better promotion, they signed with Relativity Records. Changing record labels and production duties to include Gang Starr's DJ Premier and Lil' Fame himself, the group still kept their energetic style, and gained a slightly larger following this time round. In 1998 M.O.P. released the Handle Ur Bizness EP, which was soon followed by the album First Family 4 Life. Working with the same formula, again with a heavy percentage of the record produced by DJ Premier and Lil' Fame, the album featured guest appearances by Guru of Gang Starr, Treach of Naughty by Nature, OC of Diggin' in the Crates Crew and Jay-Z. The album had the dubious distinction of being the most stolen album from New York City's HMV stores in 1998.
M.O.P.'s fan base was loyal but remained rather small until 2000, when they released Warriorz, this time on Loud Records. Mainstream radio began playing the first single, "Ante Up", produced by DR Period, with whom they had not worked with since their debut. The single was a hit and propelled the album to #25 on the Billboard200 chart. The follow-up single, the self-produced "Cold As Ice" (which featured a sample from "Cold As Ice" by Foreigner), also received radio airplay, although several of the song's lyrics had to be censored for the radio version. It was used in the UK on a TV advert for Ice White toothpaste. In 2001, a remix of "Ante Up" was released featuring Busta Rhymes, Remy Ma, and Teflon, which was also very well received. That same year, they collaborated on a song titled "Life is Good" with the pop group LFO. The song reached #40 on Billboard's Hot Singles Sales chart. Both singles continued the Posse's long-awaited mainstream success.
In 2002, Loud Records folded, leaving the group stranded. In 2003, Loud's parent label Sony/Columbia issued a greatest hits album titled 10 Years and Gunnin'. M.O.P. later joined Jay-Z and Damon Dash's Roc-A-Fella Records. Their first recording for the label was a guest appearance on Jay-Z's album The Blueprint 2: The Gift & the Curse; they were set to release their album titled Ghetto Warfare, but the eagerly anticipated album was shelved. Two other albums were recorded: one titled The Last Generation, and the other titled Kill Nigga Die Slo Bluckka Bluckka Bloaoow Blood Sweat Tears and We Out. The group also released a mixtape called Marxmen Cinema (under the name The Marxmen), as well as a self-titled rap rock album (under the name Mash Out Posse) recorded as a collaboration with heavy metal group Shiner Massive. In 2004, Damon Dash sold his share of Roc-A-Fella to new Def Jam president, Jay-Z, and kept M.O.P. on his new label, Dame Dash Music Group. The group was left feeling uncomfortable with the situation. They announced their departure from Roc-A-Fella and Dame Dash in May 2005.
In June 2005, M.O.P. officially announced their signing with 50 Cent's G-Unit Records, around the same time as Queens rap duo Mobb Deep. 50 Cent is a big fan of the group, and has stated his plans to gain the group more mainstream success. The duo completed a song with 50 Cent which was featured on the Get Rich or Die Tryin' soundtrack entitled "When Death Becomes You", and also contributed their rap vocals in a remix of "I'll Whip Ya Head Boy". Months after the signing, M.O.P. released a compilation album entitled M.O.P. Salutes the St. Marxmen, consisting of several tracks recorded while the group was signed to Roc-A-Fella. In July 2006, M.O.P released the long-shelved Ghetto Warfare.
In February 2008, M.O.P. left G-Unit Records, due to creative differences. Billy and Fame released their next album, The Foundation, in 2009 on E1 Music. The album featured production from DJ Premier, Statik Selektah, The Alchemist, and Jake One, and guest appearances from Heltah Skeltah, Busta Rhymes, Jadakiss, Beanie Sigel, Styles P and Redman. The first single from the album, "Blow the Horns" featuring Busta Rhymes, and another track called "Street Life," which is a collaboration with dancehall artist Demarco, was released on the internet.
