If you are trying to understand the Lil Peep phenomenon, which has more to do with the case of an internet celeb on Xanax than music itself, then I believe that this biopic will introduce you to who he was to the core.
Much to the ire of "old heads", 2016 was undeniably the rise of "mumble" rap, as more and more artists with little to no actual lyrical ability began to gain significant stature in the culture. But is this a sign of a new, less skilled direction for hip-hop? Or is it just a normal cycle that all genres of music go through?
