“I’m a pop enigma. I live and breathe every element in life. I rock a bespoke suit and I go to Harold’s for fried chicken. It’s all these things at once, because, as a tastemaker, I find the best of everything. There’s certain things that black people are the best at and certain things that white people are the best at.
