In the '70s, anybody who was a connoisseur of collecting vinyl had the velvet brush. Remember the velvet brush? It would clean the record, and you would only grab the record from the sides and you would carefully slide it into the jacket. I never had a velvet brush.

Hip-hop has always been chronologically misunderstood.

The first rap record came out in '79, but hip-hop began in '69.

I used to travel 200 days of the year. I had to calm it down because I have a 17-year-old daughter going on 30, and a 23-year-old son. I want to be around for them.

Hip-hop has always been chronologically misunderstood. Too many times, people are hearing the story from the second floor. Nobody's heard the story from the basement. If hip-hop was a cake, all I can tell you is the eggs, the flour, the sugar, the vanilla - the ingredient years.

That diversity of production styles and diversity of lyrical structure - I miss that.

There's no such thing as a perfect historical film.
