On this episode, KD and Eddie talk to famed engineer extraordinaire Derek "MixedByAli" Ali. They discuss his origins as an engineer, early sessions with Kendrick Lamar, Schoolboy Q and the rest of TDE, his reluctance to work with other artists, crafting sounds for artists like SZA, Summer Walker and others, his personal and work relationships with late greats Nipsey Hussle and Mac Miller, Top Dawg's reaction to mixing one To Pimp A Butterfly drum loop for an entire week, his Engine Ears platform and so much more.    Oh, and he does the impossible and chooses between Kendrick's iconic albums good kid, m.A.A.d city and To Pimp a Butterfly. Kind of.
