Please don’t be confused by the locomotive chuff-chuffs on the intro to Famoso’s new track Underground Railroad; he knows full well that the historical underground railroad had nothing to do with trains. Rather, he is alluding to the figurative train of history on which underground rap has traveled since the mid-‘80s, picking up dozens of legendary emcees along the way. The Brooklyn rapper spends his three verses fondly reminiscing about the past and name-dropping everyone from A.G. to Wu-Tang, creating a track that is not only a tribute to his calling but a fitting example of his craft. The ‘Engine Engine #9’ hook even sounds at home over Midas & Peoples’ mid-‘90s beat. Underground Railroad is featured on his new mixtape, Audio Dope.
