DJ Roc, known to his mother as Clarence Johnson, was born and raised on the Southside of Chicago, known locally as the Low End. The quot;crackquot; in the Crack Capone refers to his style of production. Like an underground chemist, DJ Roc produces variant strains of Juke music, quot;crackquot; alluding to the synapse-snapping, potentially ankle-cracking manipulation of rhythms, and the sampling, hijacking and ultra-rhythmic micro-editing of the dominant forms of contemporary African-American underground and popular music into a style born and raised on the streets of Chicago.
