If you took our “Bet You Don't Know the Rapper's Government Name” quiz—or have Money Trees memorized—you're already aware that E-40 was born Earl Stevens. On a freshly-minted single, his first feature since dropping his self-titled album back in November 2013, Ya Boy Rich Rocka pays tribute to the Bay Area legend whose classic material made him the rapper he is today. And who should show up as a guest but Charlie Hustle himself? Not only does 40 jump on the Hidden Faces' hazy, whip-ready beat to deliver a masterfully-flowed 16, but he brings his son, Droop-E, along for the ride. Fans will be able to find this dope musical homage and much more on the headliner's Allegiance LP, which is currently unscheduled. We in the Booth will, of course, keep you supplied with the latest news and tunes leading up to its eventual release.
