"Popular music is nothing if not dialogic, the product of an ongoing historical conversation in which no one has the first or last word. The traces of the past that pervade the popular music of the present amount to more than mere chance: they are not simply juxtapositions of incompatible realities. They reflect a dialogic process, one embedded in collective history and nurtured by the ingenuity of artists interested in fashioning icons of opposition" (BN 148).
