Paul Michael Slayton (born March 11, 1981), better known by his stage name Paul Wall, is an American rapper. He is currently affiliated with Swishahouse Records, having released several albums under the label as well as collaborating with other rappers signed to the label. He was formerly musical partners with rapper Chamillionaire releasing several collaborative albums including the independently released Get Ya Mind Correct. In 2005, he was signed to Atlantic Records and became successful with his major-label debut The Peoples Champ. Get Money, Stay True followed in 2007.

Wall attended Jersey Village High School and studied mass communications at the University of Houston for three years. After proposing to do promotions for Michael "5000" Watts' company, Swishahouse, Chamillionaire and Paul Wall came to Watts' studio, KBXX. Paul & Chamillionaire convinced Watts to let them rap on his radio show and put the verses on one of his mixtapes. That mixtape was titled Choppin Em Up Part 2, which was released in mid 1999. The freestyle became so popular in the streets that Chamillionaire and Paul Wall became regular staples on Houston's mixtape circuit, appeared on several of Watts' mixtapes and became permanent members of Swishahouse.

Just-Ice (born Joseph Williams Jr.) A former bouncer at punk clubs, Ice was one of the first of the New York MCs to embrace hardcore rap, and when he burst out of Fort Greene, Brooklyn, as Just-Ice, he gained instant notoriety. Muscle-bound, tattooed, aggressive—he resembled Mike Tyson in more than just looks—and with a mouthful of gold teeth, which was the style in his neighborhood. His slickly produced debut single "LaToya/Put that Record back On" was an instant hit. However, a more down-and-dirty sound could be found on the 12" B-Side track, "That Girl is a Slut," which, for the time, was relatively profane and owed at least some inspiration to Doug E. Fresh and Slick Rick's "La Di Da Di." Released soon afterward, his debut album Back to the Old School proved he was more than just a pretty face. It came out on the independent New York label Fresh/Sleeping Bag label in 1986 and sounded like no other hip-hop album, thanks to his fast, forceful rhymes, human beatbox DMX, and the distinctive production of Mantronix's Kurtis Mantronik. Ice was also one of the first MCs to embrace the teachings of the Nation of Gods and Earths on a recording, as well as being a pioneer in incorporating dancehall-style toasting into hip-hop rhymes. The album is best known in Hip Hop circles for the single "Cold Gettin' Dumb"; the universally known beat can be found reworked on Redman's single "It's Like That" featuring K-Solo, from the 1996 album, Muddy Waters.
