From the beginning of Nas' career, producer Large Professor has been a steady collaborator, supplying the Queensbridge MC with three beats for his breakout debut 'Illmatic.' Though it's been nearly two decades since they began working with one another, that hasn't stopped the two from putting in work in the studio. The producer, whose real name is William Paul Mitchell, recently revealed that he's sitting on a bunch of joints recorded with Nasty Nas, and that an a full-length collabo album might not be far off.

"That's already there. We got mad joints in the can," he told Forbez DVD. "It's a matter of just when we're going to release them, when we want to drop jewels on them."

Large Pro, who was part of the heralded group Main Source, produced the beat on Nas' first public appearance on the track 'Live at the Barbeque,' a cut included on 1991's 'Breaking Atoms.' Their working relationship continued when Pro produced 'One Time 4 Your Mind,' 'Halftime' and 'It Ain't Hard to Tell' on Nas' 1994 debut 'Illmatic,' reuniting for his 2001 comeback album 'Stillmatic' for the tracks 'Rewind' and 'You're Da Man.'

Pro nabbed Nas for his 2002 solo debut '1st Class,' which also featured guest appearances from Q-Tip and Busta Rhymes. Since then, Pro has continued on to release several instrumental LPs as well as two more solo albums. He most recently produced Joell Ortiz's single 'Ohh' off the freshly released 'Free Agent' album.
