One day after his “i” release, Kendrick Lamar isn’t out to give the spotlight up. But if anybody’s testing him for it, it’s not who you’d expect.

On Big Boy’s Neighborhood, K-Dot goes truly off the dome through 25 years of instrumentals, ranging from Nas/James Brown, to State Property, to Jay Z, to Dr. Dre. Along the way, Kendrick offers some beautiful imagery of his city and youth, and some strong metaphors in doing so. He emphasizes about halfway that he’s truly coming improvisational. The TDE artist keeps making mention of Ruthless, Death Row, and Eazy-E, something his label was controversially compared to in a GQ cover story.

With Kendrick shaking things up as expected, Big Boy jokes—assisted by Lamar, that the Los Angeles radio/Power 106 mainstay actually writes the Compton MC’s lines.

Uncharacteristically, over Nas “I Can,” Big Boy GOES IN for an old school-themed, true freestyle. It’s schoolyard battle rap at its best, as Big Boy, kiddingly, tells the story of Kendrick coming to him a decade ago, and the morning show master doing the rest—from the name-change, to linking him with Top Dawg, to fixing some “wack” stuff.

Kendrick Lamar may be the most impressed witness in the room, in this humorous, unexpected, and incredibly captivating Hip-Hop moment.

Is this the best radio show freestyle of 2014, or too early to call?

Is it safe to say that above Sway Calloway, Tony Touch, and Big Tigger, that Big Boy just might have the finest freestyle bars for a radio platform? What do you think?
