With a sonic foundation that typically relies on sped-up vocal samples of classic soul songs, Kanye West has emerged as one of hip-hop's premier produc¬ers. In the last few years, he earned production credit on a number of smash singles, including Jay-Z's "Izzo (H.O.V.A.)," "Girls, Girls, Girls," and ''’03 Bonnie & Clyde," and more recently, on Alicia Keys' soulful "You Don't Know My Name," Twista's seductive "Slow Jamz" (on which West also raps), and Ludacris' forceful "Stand Up." But the Chicagoan's master plan was to segue from A-List pro¬ducer to headlining rapper. Mission accomplished with “The College Dropout,” one of the best rap albums of the year.

Built off of Chaka Khan's "Through the Fire," West's first single, "Through the Wire," details his near-fatal 2002 car crash in Los Angeles and has enjoyed a slow bum on radio stations across the country. But it was the song's good-natured video, which shows West in various stages of recovery from the accident, that endeared him to¬ hip-hop fans as a rapper. His subsequent light-hearted appearance on "Slow Jamz" demonstrated that West had the same type of inventiveness as a rapper that he has as a producer. On “The College Dropout,” both of his skills are on full display, as he delivers insightful, comedic lyrics about his affinity for material items ("All Falls Down"), his need for a religious foundation ("Jesus Walks"), and how gold-digging women can land the millionaire man of their dreams ("The New Workout Plan"). West's flow is sometimes awkward, giving him a charmingly unrefined style as a rapper, but his powerful production always delivers, as his soulful soundscapes, always crystal clear and remarkably crisp, make for a stirring sonic experience.

As Chicago hip-hop enjoys a commer¬cial renaissance thanks to the success of West and Twista, the city's underground acts show that the Windy City is chock¬full of top-tier talent. One such artist is Diverse, whose strong debut “One A.M.” is somewhat like an underground version of West's album. Whereas West has big cho¬ruses and such A-List guests as Jay-Z and Ludacris, Diverse rocks over scratch¬-backed, gritty boom-bap beats, and teams with such lyrical lords of the underground as Jean Grae and Vast Aire. Diverse's sonic tapestries are so intoxicating that it may take multiple listens to appreciate the impact of his lyrical skill. He flexes his sto¬rytelling abilities on the non-gangster look at life in the ghetto on "Ain't Right" and relates the stress of living in a society where everyone isn't treated equally on "Under the Hammer."
