He was beloved by many in New York and throughout rap's independent ranks, having collaborated with such venerable artists as Talib Kweli, Immortal Technique, Wordsworth, Del the Funky Homosapien, Murs, Jean Grae, Royce da 5'9" and more. Diaz leaves behind a wife and two sons. Just this week, he and his wife announced that they were expecting a new baby girl.
