UTD brings a Fugees-style vibe, combining both male and female vocals that mesh intermittent crooning with absolute lyrical grit. Producers Diamond D. and Showbiz keep a hard edge grinding throughout, adding an appropriate ruggedness to the album's gutter feel. Heavy-handed bass loops guide the unabashed verbal barrage, marked with periodic jazz melodies that play well to the sing-song style that Mos Def has embraced even more so in his later work.
