In the 1990s, two brothers of Mexican descent, Sick Jacken and Duke, formed the hip-hop group named the Psycho Realm. Born and raised in the Pico-Union barrio of Los Angeles, the Psycho Realm has produced radical critiques of policing, intracommunal violence, and the potential insurgency of the oppressed residing in the barrios of L.A. In this chapter, I analyse six songs of Sick Jacken’s solo projects in conversation with Mike Davis’s analyses of “Fortress L.A.” The music of Sick Jacken and the Psycho Realm, I argue, provides a first-hand account of Davis’s description of the carceral city through voices emerging from within it. Jacken imagines Pico Union as a barrio within “Fortress L.A.”. They describe the actual urban conditions that emerge from the uneven development of racial capitalism in a city fraught with racialized class contradictions while dialectically imagining a rebellious response by the masses.
