DJ Premier

No more than three producers (Dr. Dre, RZA, and Prince Paul) can test DJ Premier's status as the most important trackmaster of the '90s, and no style is more distinctive. Aggressive and raw, a Premier track was an instantly recognizable soundclash of battling loops and heavy scratching -- all of them perfectly timed -- that evoked the sound of Brooklyn better than anyone. Besides helming tracks for his main concern, Gang Starr, since their 1989 debut, Premier's productions appeared on many of the East Coast's most important records: Nas' Illmatic, the Notorious B.I.G.'s Ready to Die, Jay-Z's Reasonable Doubt, Jeru the Damaja's The Sun Rises in the East, and Mos Def's Black on Both Sides.
