Around the same time Cam’ron and Kanye West were crossing paths in Baseline and Roc The Mic Studios in New York City, A-Trak was ‘Ye’s DJ. The mid-2000s found Cam famously at the Roc for a three solo album deal, while Kanye’s own career skyrocketed. Shortly thereafter, A-Trak, who had come up in the turntablism scene, winning ITF and DMC championships, started working with Hell Rell, J.R. Writer, and some of the other members of The Diplomats.

Years after the Roc era, the two, now rooted in their own followings, labels, and ventures, are back in action together. With the Federal Reserve EP coming (also featuring beats by Party Supplies), this is “Humphrey,” which sounds like a crystal ball-informed holdover from Purple Haze.
