Man, I fukked with a ton of his early stuff heavy. He and Currensy have some fire together. Smoke DZA, Meyhem, Action...but the past few years I've definitely liked his output a lot less. Not sure why. I had been anticipating the Boldy collab project for a long time and definitely felt let down by it. I might give it another listen.
Also, re: Tea in China...the Alc project show why he's a producer and not just a beatmaker. It's clear on their projects together that they bring more out of each other.
