 Two years later the group released their debut album, "Da Dirty 30", which featured three singles "Just Another Case" "Pronto" and "Bubblin'".

Business as Usual is the third album from Hip Hop duo EPMD, released December 18, 1990 and their first on leading rap label Def Jam as a result of being signed over (along with Nice & Smooth) from their former label, Fresh Records.
 This album was also the first release by Def Jam as an imprint under its new Rush Associated Labels subsidiary, which allowed founder Russell Simmons more control and more ownership over its material, as the masters for proper Def Jam releases at that time were primarily owned by Sony Music's Columbia Records.
 Business as Usual was not as acclaimed as their first two albums, but was not considered to be a failure either.
 One notable aspect here was the debut of future Hip Hop star Redman, who appears on the tracks ""Hardcore"" and ""Brothers on My Jock"".
 Three singles were released from the album, "Gold Digger", "Rampage (Slow Down, Baby)" featuring LL Cool J and "Give the People".
 In 1998, the album was selected as one of The Source's 100 Best Rap Albums.
Uptown 3000 was a Korean American hip hop duo on the record label The Machine Group CEO Alvin & Calvin Waters which consisted of Carlos Galvan aka "Cali-Mexci" and Steve Kim aka "Kwon".
 The duo was a spinoff of Uptown, a Korean hip hop group which was active in the late 1990s whose sales reached 6 million.
 The duo is considered defunct as the original Uptown made its comeback in Korea in 2006, which Kim and Galvan were a part of.
 The group has been credited with being the first Korean hip hop group to closely resemble anything similar to American style hip hop.
EPMD is an American Hip Hop group from Brentwood, New York.
 The group's name is a concatenation of the members' names "E" and "PMD" or an acronym for "Erick and Parrish Making Dollars", referencing its members, emcees Erick Sermon ("E" a.k.a. E Double) and Parrish Smith ("PMD" a.k.a. Parrish Mic Doc).
 During an interview on college radio station WHOV in 1987, Parrish Smith stated that the name evolved from the original: "We were originally known as "EEPMD" (Easy Erick and Parrish the Microphone Doctor), but chose to go with EPMD because it was easier to say."
 He also stated that they dropped the two "E's" because N.W.A.'s Eric Wright was already using "Eazy-E" as his stage name.
 The group has been active for 31 years (minus two breakups in 1993 and 1999), and is one of the most prominent acts in east coast hip hop.
 DJ K La Boss and DJ Scratch were DJs for the group and their current DJ is DJ Diamond J
"Rampage" (a.k.a. "Slow Down, Baby") is the second hit single released from EPMD's third album, "Business as Usual".
 EPMD's new-found labelmate, LL Cool J contributed a verse on the song, while Pete Rock would provide the remix to the song.
 "Rampage" found its greatest success on the Rap charts, peaking at #2.
Run–D.M.C. is the debut studio album of American hip hop group Run–D.M.C..
 Produced in 1984, it was considered groundbreaking for its time, presenting a harder, more aggressive form of hip hop.
 The album's sparse beats and aggressive rhymes were in sharp contrast with the light, funky sound that was popular in hip hop at the time.
 With the album, the group has been regarded by music writers as pioneering the movement of new school hip hop of the mid-1980s.
 The album was reissued as a "Deluxe Edition" in 2005 with four bonus tracks.
R.A.C.L.A. (an abbreviation of Rime Alese Care Lovesc Adânc - Handpicked Rhymes with a Deeper Meaning) is a Romanian hip hop group, founded in 1993 in Bucharest.
 Initially consisting of brothers Călin "Rimaru" Ionescu and Daniel "Clonatu'" Ionescu, the group released the first Romanian hip hop album in 1995 on Kromm Studio, an independent record label.
 One of first and most critically acclaimed hip hop acts in Romania, it has been through numerous personnel changes after Clonatu's departure from the group in 1998, with Rimaru remaining the sole constant member throughout the years.
 Originally known among its fans as a hardcore and political rap group, they would later gain a larger fan base in their native Romania following their collaboration with pop singer Anda Adam in 1999.
 In the mid and late 1990s, R.A.C.L.A. also gained notoriety for their involvement in a violent conflict with gangsta rap group B.U.G. Mafia and some of their affiliates at the time, such as La Familia and Il-Egal.
 The dispute initially produced a number of diss tracks from both sides and would later lead to physical altercations between members of the groups.
 While never officially announcing their hiatus, the group became largely inactive for a number of years following the release of their fifth album in 2005 and group member Connect-R's departure in 2006.
 Rimaru made a number of infrequent appearances as a solo artist and, as of 2014, has returned to performing under the group name, while also recruiting DJ GreWu, DJ Semplaru and rappers EyeKon and later TKE and Boka, as touring members of R.A.C.L.A.
