Mozzy has always been a rapper’s rapper, and Untreated Trauma features a who’s-who of the independent circuit: YFN Lucci, Celly Ru, and E Mozzy. However, the feature that lingers longest is the one that isn't there. You can feel the ghost of the fallen—the friends he mentions in passing. The album is populated by voices asking Mozzy to "stay down" or to "get out," creating a crowded, claustrophobic listening experience. You unzip the file and suddenly you’re in the living room with a dozen traumatized survivors, all talking over each other.
