(DUB) In terms of DJing (or toasting—the Jamaican form of rapping) Brooklyn's Dr. Israel sticks with the tradition. He wants equal justice for all; he calls for the fall of Babylon; he believes that the youths of the ghetto are ready for what Willie Williams famously called "Armagideon Time." Musically, however, Dr. Israel breaks with the Jamaican tradition. In his records, the lines between jungle, rock, techno, hiphop, dub, and soul dissolve, and what is left is a wonderful mess of bass and beats.
