OAKLAND, Calif. -- LeBron James and Kevin Durant are dominating on the court as they try to inch their respective teams closer to obtaining the Larry O’Brien trophy, but what may surprise some is that they used to be brief teammates dominating in the studio.

As legend has it, stashed away somewhere is a 6-year-old, never-before released hip-hop track by James and Durant.

League sources informed ESPN that the Cleveland Cavaliers and Golden State Warriors superstars collaborated on the track during the lockout in 2011 while Durant, then a member of the Oklahoma City Thunder, was visiting James, who had joined the Miami Heat, for workouts in Akron, Ohio.

Both players are music junkies, and in between workouts they decided to kill some time by writing their own lyrics and heading to the booth, sources told ESPN.

One person who has heard the song says he recalls Durant rapping the first verse, James hopping on for the second and then Durant finishing it off.

The song's title and theme are unknown, as are its whereabouts. Durant, who produces beats in his spare time, is believed to have provided the instrumentals.

When approached about its existence, James and Durant, to a moderate extent, confirmed that there is such a track before bursting out into laughter without further comment. There are no current plans to release the song to the public.

One individual who listened said it was “a quality track” and added that the lyrics were “surprisingly well-crafted and delivered.” It was so aesthetically pleasing that there were discussions about it being featured in the 2012 film "Thunderstruck," which starred Durant.

“I heard the track years ago during post-production for ‘Thunderstruck,’” said agent Eric Goodwin, who executive produced the film and once represented both Durant and James. “It was very good. I suggested submitting it to Warner Brothers for the movie soundtrack, but KD wanted to keep it private.”

At this point we don't know how two of the game’s best basketball players blend together on a hip-hop track. Right now, they want to be associated strictly with their artwork on the hardwood, not in the studio.
