Lawrence Krisna Parker (born August 20, 1965), better known by his stage names KRS-One (an acronym for Knowledge Reigns Supreme Over Nearly Everyone), and Teacha, is an American rapper. At the 2008 BET Awards, KRS-One was the recipient of the Lifetime Achievement Award for all his work and effort towards the Stop the Violence Movement as well as the overall pioneering of hip hop music and culture.

Lawrence Parker was born in Flatbush, Brooklyn, New York during the summer of 1965. Parker left home at 16 to become an MC, coming to live at a homeless shelter in the South Bronx where he was dubbed Krishna by residents because of his interest in the Hare Krishna spirituality of some of the antipoverty workers. By the time he met youth counselor Scott Sterling, he was also writing graffiti as KRS-One (Knowledge Reigns Supreme Over Nearly Everyone). Together he and Sterling, a.k.a. DJ Scott La Rock eventually created Boogie Down Productions, releasing their debut album, Criminal Minded, in 1987. KRS-One has been a vegetarian since his youth.

Marlon Williams (born September 30, 1962), better known as Marley Marl, is an American DJ and record producer, who is considered one of the most important and influential hip-hop producers in the history of hip hop.

In Hip-Hop's Golden Age, Marley Marl was the house producer of the Juice Crew, known for The Bridge Wars, a feud with Boogie Down Productions seen as one of the earliest and most influential hip hop beefs. The Juice Crew included Big Daddy Kane, Biz Markie, Roxanne Shanté, Kool G Rap & DJ Polo, Craig G, MC Shan and Masta Ace, and produced many songs for outside artists including King Tee, LL Cool J, and Lords of the Underground. He was also an important figure in the careers of Eric B. & Rakim, producing their first hits "My Melody" and "Eric B Is President".

Marl was the first to sample a breakbeat and reprogram it, which he did with The Honey Drippers' "Impeach the President" breakbeat on the MC Shan single "The Bridge" from 1985. This was an extremely important feat as it completely changed the way hip hop beats were made, as well as other sample based genres. In his early records, Marl mixed James Brown samples and synthetic beats in a fashion previously unheard of, for the most part.

Philip Martin (born October 31, 1978 in Inglewood, California), better known as Bishop Lamont is an American rapper from Carson, California. He was signed to Dr. Dre's Aftermath Entertainment record label but left in 2010.

Martin started rapping at age thirteen. Dr. Dre met Martin while on set filming The Game's music video for "Dreams". After giving him praises on an L.A. radio station, Dr. Dre signed Martin in 2005. Martin was featured in The Source's Unsigned Hype section, but he was already signed to Aftermath by the time the issue hit stands.

According to Martin, Dr. Dre said that along with Eminem, Martin is the only other rapper that made him uncomfortable. Dr. Dre said that this is due to his protégé's controversial and political lyrics.

Martin is credited for his numerous soundtrack contributions. He has appeared in the soundtrack for the video game True Crime: Streets of LA. He can also be heard on three EA Sports video games. The tracks "The Best" and "We Got Next" are included in Madden 2007 and NBA Live 06, respectively. Also, the track "I'm a Soldier" was included in NFL Street 2. His song City Lights was in The Midnight Club: Los Angeles soundtrack. In addition, Martin has the title track "Welcome to Havoc", featured in Havoc, a film starring Anne Hathaway.

Dallion Priest, better known as Mad Lion, is a dancehall, ragga musician and rapper. He frequently collaborates with fellow hip hop artist KRS-One — most recently on a DVD promoting the Temple of Hiphop. The recipient of the 1994 Source award as Reggae Artist of the Year, he has inspired similar-sounding recordings by such artists as Ini Kamoze, Capleton, and Rayvon.

Priest was born in London. Shortly after moving to Brooklyn, New York, he met reggae performer Super Cat at Super Power Records. At Super Cat's suggestion, he adopted his professional name, an acronym for Musical Assassin Delivering Lyrical Intelligence Over Nations. He blended ragga and hip-hop, and went on to work with KRS-One, with whom he worked throughout the 1990s. His earliest success came in the mid-1980s when he applied his hip hop rhythms to Shabba Ranks' hit single "Jam". His début single "Shoot to Kill" was successful in New York and he reached a wider audience with "Take It Easy", which became the title track of his début album in 1994. He contributed to Salt-N-Pepa's 1997 album Brand New. In 1997 he topped the US reggae chart with "Carpenter".
