Large Professor

William Paul Mitchell (born March 21, 1972), better known by the stage name of Large Professor (also Extra P. and Large Pro), is an American rapper and music producer.

Based in New York City, he is known as a founding member of the underground hip hop group Main Source and as a mentor and frequent collaborator of Nas.

About.com ranked Large Professor at No. 13 on its Top 25 Hip-Hop Producers list.

William Paul Mitchell was born in Harlem, New York City, and raised in Flushing, Queens, New York City, where he attended John Bowne High School.

Large Professor started making his earliest beats with two turntables, a Casio SK-1 sampler, and pause-tape cassettes before his mentor Paul C taught him how to use an E-mu SP-1200.

During his pause tape phase he noted that some of his techniques were different than those of other producers.

"I was trying to catch it from a different part of the record. I would catch it from the hi-hat when dudes were just catching it from the one kick. I would catch it from the third hi-hat and be flipping it."

In 1989 he joined the group Main Source, which also included Toronto natives K-Cut and Sir Scratch.

In 1990 Large produced three tracks for Eric B.. & Rakim's Let the Rhythm Hit 'Em, including "In the Ghetto".

To make "In the Ghetto", he sampled directly off of a cassette tape of sample ideas Paul C had made for Rakim.

During and after his tenure with Main Source, he worked with Pete Rock & CL Smooth, and he produced a number of tracks for Nas, Busta Rhymes, Masta Ace, The X-Ecutioners, Tragedy Khadafi, Big Daddy Kane, Mobb Deep, A Tribe Called Quest, and others during the 1990s.

During this time he handled a significant amount of production on several projects for other artists.

Main Source recorded one album with Large called Breaking Atoms, which was released in 1991.

It included hits such as "Just Hangin' Out", "Looking at the Front Door", and featured Nas' first public appearance on a track called "Live at the Barbeque", along with Akinyele and Joe Fatal.

Large Professor now considers "Looking at the Front Door" one of the most emotional records of his career, later saying "That's a deep record. At that time in life, I was eighteen years old. It was a kid with a pure heart, just writing, and putting his soul out there for the world."

In 1992, their success allowed them to record "Fakin' the Funk", a track on the White Men Can't Jump motion-picture soundtrack.

Because of business differences, Large and Main Source quietly parted ways and Large went on to sign with Geffen Records.

In 1993 he produced Akinyele's entire Vagina Diner album, which experienced some modest commercial success at the time of its release.

Though the album did well at first, The Source later wrote an article criticizing the song "I Luh Huh", in which Akinyele considers pushing his pregnant girlfriend down the stairs as a form of abortion.

The ensuing backlash for the controversial lyrics hurt the album's performance.

Akinyele wrote a response in the next issue defending the song and pointing out that the violent ideas in the songs are just thoughts, and he ends the song by saying "Just cause I talk this shit don't get me wrong, Yo, I still luh hur."

Large Professor also produced "Keep It Rollin'" on A Tribe Called Quest's Midnight Marauders not long after he left Main Source.

This was a major moment in his career that helped him reach a new level of credibility and exposure as a solo artist.

In 1994, Large Professor produced three of the ten songs on Nas's Illmatic ("Halftime", "One Time 4 Your Mind", and "It Ain't Hard to Tell"), the most of any producer involved with the album.

According to an interview with Busta Rhymes, the "Halftime" beat was originally intended for him.

Though he liked the beat, he didn't end up using it and later regretted it after hearing "Halftime".

While describing the making of the song in an interview Large Pro said, "I mean, we just wanted to put something gritty out there to the world, and those drums—that's what it was at that time. It was that gritty, muffled out, because the Hip Hop that we grew up with… We grew up with park jam tapes and things like the fidelity of these tapes."

He was so instrumental in the making of Illmatic that Nas wanted to give him an executive producer credit, but he refused.

In 1996, Large Professor completed his debut solo album The LP for Geffen Records.

It was promoted by the singles "The Mad Scientist" and "I Juswannachill".

In 2001, Large Pro produced "You're da Man" and "Rewind" for Nas's Stillmatic album.

He first played Nas the beat for "You're da Man" while Nas was working on Nastradamus a few years prior.

Nas chose the beat but decided to save it for a later project.

Large Professor also used the same vocal sample from the chorus on the song "The Man" for his 1st Class album.

After several delays, the album was shelved and later released as a bootleg version in 2002.

On December 22, 2002, at a concert in Toronto, the original members of Main Source performed together for the first time in nearly 10 years.

An official release of the album finally came out in 2009, thirteen years after its original intended release date.
