Chicago rhymer Diverse's name has been bouncing around for a hot minute now. Last seen knocking mighty Mos Def straight off the wax of Chocolate Industries' Urban Renewal comp, it's now One A.M. and Diverse is ready to step up and slam the mic down 'til it's broke. RJD2 heats the beats for "Certified," with Diverse verbally dueling a dirty guitar riff that could pass for vintage Keith Richards. Diverse brings talented friends like Madlib and Lyrics Born in for variety, but he hardly needs the help. His fast, staccato style makes up for a lack of vocal range by packing in the rhymes and nimbly leaping from topic to topic, jumping from furious battle rhymes to the reflective relationship-related verses of the Prefuse 73-produced "Just Biz." Diverse indeed.
