(TRUE HIPHOP) By the middle of the '90s, every hiphop producer was imitating Pete Rock's style of echoing looped horn sets, piano fragments, and floating chants. His sound could be heard on the streets of Paris (Supreme NTM's Paris Sous les Bombes), Tokyo (DJ Krush's Big City Lover), and New York City (Queen Latifah's Black Reign). To this day, his impact on hiphop can be felt in the music of local producers like Vitamin D and DJ Sabzi. Pete Rock is the number-one soul brother.
