Words from Paul Rosenberg
““Underground,” that was one of my favourites because [Em was] just spitting like [he was] back at the hip-hop shop. It was sick, and I was so happy that [he] wasn’t brain-damaged [from the overdose] and disabled from rapping like that again. When I listen to it now, it still gives me chills.
