Jack and older brother Duke make up the chicano (Mexican-American) hip-hop group that has long reigned as the undisputed king of the Los Angeles underground scene, cultivating an army of devoted fans known as the Sick Soldiers. The first seeds of Psycho Realm were sown in the tough downtown Pico-Union neighborhood, right across the street from Doheny Park. First-generation Americans and the eldest two of the four Gonzalez boys, Jack and Gustavo, a.k.a. "Duke," grew up in the contentious neighborhood in the mid- and late-1980s.
