Hip-hop (and other things) is about, as it were, rap, but also some other things. It's a smart, fun, funny, insightful book that spends the entirety of its time celebrating what has become the most dominant form of music these past two and a half decades. Tupac is in there. Jay Z is in there. Missy Elliott is in there. Drake is in there. Pretty much all of the big names are in there, as are a bunch of the smaller names, too.
