Although the crusty beats and slaps on DJ Cer’s Throwback Attack might gall some listeners, the stars of this compilation-pioneers like Jungle Brothers and T La Rock-sound more infectious than most hot rappers du jour. Moreover, you don’t need an encyclopedia to understand Dimples D (“Sucker DJ”) or Cash Money and Marvelous (“Ugly People Be Quiet”), who built their rhymes around punchlines, rather than concepts. If you favor authenticity over ideology, and scrappy boom-bap over sophistication, you’re in for a treat: Throwback Attack is a grimier, more nuanced flashback mix than you’d find on your FM dial.
