Darqwan spotlights his dubstep imprint by putting his “Nocturnal” into the hands of remixer Geeneus, who keeps the bass rumble intact while toughening up the drumbeat. After darkening the wah-bass melody of his own breakstep jam, “Said the Spider,” ‘qwan spotlights Markone, who gives his own “Tribesmen” an electro-fied, subterranean rub. As they used to tell Baryshnikov: nice package.
