Grammy-winning producer 9th Wonder breaks down the history behind “Threat,” the song he produced for Jay-Z’s Black Album.

“I played 29 beats for him,” 9th says about his first session with Jay. None of the beats led to a collaboration. Eventually, 9th had to whip up something from scratch, based on a sample suggestion from Jay. If you’re a beat junkie like yours truly, you’ll appreciate all the history lessons and pro tips 9th drops along the way.

Hit play for the full story.
