Although it's unclear if they will produce the entire album, Kanye West and Dion "No I.D." Wilson are hard at work making tracks for Jay-Z's "Blueprint 3," according to West's management.

West and Jay-Z debuted one of their collaborations, "Jockin' Jay-Z," last week during West's Glow in the Dark tour stop at New York's Madison Square Garden.

No I.D., who, like West, is a Chicago producer, started his career in the early 1990s and is best known for his work with Common. He also works closely with Jermaine Dupri's label, So So Def, as a co-producer.

Def Jam has not yet announced a release date for "Blueprint 3," Jay-Z's last studio album for the company before he begins recording for Live Nation.
