Derrick was a very shy person in public, but his music was very clear and very powerful and his voice came through in that way. He was a really fast learner; I don't think he'd been producing for more than seven or eight years total, but in that time the amount of music he made is pretty astounding. Most of it is unreleased, I don't know that any of it will be released, but he was able to finish--he made finished products, and that's what makes a producer a skilled producer. Thousands of people every day make things that they don't finish, because finishing things is what is so hard about being a producer. That final 10% takes 90% of the time, and Derrick had a gift for finishing things quickly in a very protracted process. His particular process is what gave him that sound, and working with him the little bit that I did I saw that he took way more time in that process and got a specific result. He wasn't cutting any corners. He did it in the most painstaking way.
