Oddisee’s The Good Fight is bringing a lot of attention to the Diamond District cofounder. Despite the fact that he’s been making music on a large scale for more than a dozen years, Heads are still discovering the Mello Music Group mainstay.

In an interview with Respect Due, Oddy’ opens up about the mysterious J. Cole collaborations. Cole has recorded tracks to some of Oddisee’s 2011 Rock Creek Park instrumentals. Additionally, the platinum star sourced some material from Oddisee, who has also worked with J-Live, Bumpy Knuckles, and Foreign Exchange.

However, fans may not have heard a song that could be a game-changer in the career of this dedicated musician. In a new conversation with Respect Due TV, Oddisee explained.

“I did like six, seven songs with J. Cole, total,” confirmed the artist born Amir Muhammad. “I know we did three or four [original songs]; then he did some stuff with Rock Creek beats. But he has played me two of the tracks—one of them I have. The other one he played me was to another beat I made, it featured Kendrick [Lamar] on it. So there is a track by me, featuring J. Cole and Kendrick Lamar. Will it ever see the light of day, I have no idea.” He added, “I’ve heard it.”

In the same interview, Oddisee said that after attending a J. Cole concert, he was direct messaged by the North Carolina native on Twitter. The next day, Oddisee partook in a 12-hour recording session for what would become 2013’s Born Sinner. While the session did not result in album material, the independent mainstay reveals that his synergy with Cole informed the acclaimed sophomore album.

Previously, Cole and Lamar have worked together on several songs, in varying capacities—most notably 2011’s “HiiiPower.”

If the power-cypher reaches the surface, will Oddisee’s Good Fight get the knockout response many believe it deserves?
