“The story of the rapper and the story of the hustler are like rap itself, two kinds of rhythm working together, having a conversation with each other, doing more together than they could do apart. It's been said that the thing that makes rap special, that makes it different both from pop music and from written poetry, is that it's built around two kinds of rhythm. The first kind of rhythm is the meter. In poetry, the meter is abstract, but in rap, the meter is something you literally hear: it's the beat. The beat in a song never stops, it never varies. No matter what other sounds are on the track, even if it's a Timbaland production with all kinds of offbeat fills and electronics, a rap song is usually built bar by bar, four-beat measure by four-beat measure. It's like time itself, ticking off relentlessly in a rhythm that never varies and never stops.When you think about it like that, you realize the beat is everywhere, you just have to tap into it. You can bang it out on a project wall or an 808 drum machine or just use your hands. You can beatbox it with your mouth. But the beat is only one half of a rap song's rhythm. The other is the flow. When a rapper jumps on a beat, he adds his own rhythm. Sometimes you stay in the pocket of the beat and just let the rhymes land on the square so that the beat and flow become one. But sometimes the flow cops up the beat, breaks the beat into smaller units, forces in multiple syllables and repeated sounds and internal rhymes, or hangs a drunken leg over the last bap and keeps going, sneaks out of that bitch. The flow isn't like time, it's like life. It's like a heartbeat or the way you breathe, it can jump, speed up, slow down, stop, or pound right through like a machine. If the beat is time, flow is what we do with that time, how we live through it. The beat is everywhere, but every life has to find its own flow.Just like beats and flows work together, rapping and hustling, for me at least, live through each other. Those early raps were beautiful in their way and a whole generation of us felt represented for the first time when we heard them. But there's a reason the culture evolved beyond that playful, partying lyrical style. Even when we recognized the voices, and recognized the style, and even personally knew the cats who were on the records, the content didn't always reflect the lives we were leading. There was a distance between what was becoming rap's signature style - the relentlessness, the swagger, the complex wordplay - and the substance of the songs. The culture had to go somewhere else to grow.It had to come home.”
