Twista’s hip-hop hit “Slow Jamz” is one of those singles that grabs you by the ear the first time you hear it. An ode to R&B love ballads known as “slow jams,” it features a sped-up sample from Luther Vandross’s 1981 version of “A House Is Not a Home” and salutes such other bedroom-soul staples as Marvin Gaye, Anita Baker and Earth, Wind and Fire. “Let me get your sheets wet/Listening to Keith Sweat,” raps Twista over the bump-and-grind groove. There is nothing else on the Chicago rapper’s third disc as catchy or clever as “Slow Jamz,” however, and the overlong CD has its share of filler, such as the tired “Pimp On.” Still, with his rapid-fire rhymes, Twista keeps the fun factor high on party cuts like the liquor-loving “Drinks” and the Nellyesque “Badunkadunk,” a humorous paean to big booties. Guest appearances by Ludacris, R. Kelly and R&B singer Anthony Hamilton add flavor to this Kamikaze.
