Burks signed with EMI to release three studio albums: Word to the Jaz (1989), To Your Soul (1990) and Kingz Kounty (2002).

[3] He has also been credited with production work for other artists including Puff Daddy, Rakim, Usual Suspects, GZA, Kool G Rap, Queen Latifah, M.O.P., and Group Home, among others.

I put out a song in 1985 called "HP Gets Busy" on our own label (my manager at the time, Jack Walker and I), featuring two of my comrades from Long Island, NY, and my young apprentice, Jay Z.

He helped me get a single deal on Tommy Boy Records after I collaborated on a song with him called "My Fila" (a response to Run DMC's, "My Adidas").

Joining him on the trip was Jay-Z, as well as future Murder Inc Records CEO and producer Irv Gotti, who was Jaz-O's DJ at the time.

[9] The single "Let's Play House"/"Buss the Speaker" peaked at number 26 on the Billboard Dance Club Songs chart.

Sometime after the album was released, Jaz-O was dropped from his record label and began to spend time working behind the scenes as a producer.

At some point, Jaz-O connected with The Lox, and produced a demo tape for the group, which would become instrumental to the start of their successful career.

Becoming a supporter of the group, Blige would pass the demo tape on to Bad Boy CEO Sean "Puffy" Combs while on a tour with Jodeci.

Jaz-O produced, and was featured on "Ain't No Nigga," the second single from Jay-Z's 1996 debut album, Reasonable Doubt.

It is rumored that they did not trust Roc-A-Fella Records CEO Damon Dash and label co-founder Kareem "Biggs" Burke.

On the song, in which they rapped over Styles P's "Good Times" instrumental, and later on his album The Blueprint 2: The Gift & The Curse, Jay-Z states: "I'ma let karma catch up to Jaz-O."

During the long-standing feud between mentor and protégé, Jay-Z would still give Jaz-O credit for his success (while dissing him at the same time) as heard in the song "I Do It For Hip Hop" on Ludacris's Theater of the Mind album, where Jay-Z says "Shout out to Grand Master Flash and to Caz and even Jaz's bum ass".

In late August 2009, Jaz-O was featured on another song dissing Jay-Z, titled "Gangstas Ride" with West Coast rapper, The Game.

[21] On February 7, 2020, Jaz-O released an extended play (EP) titled The Warmup, on Kingz Kounty Media Group.

[27] Besides being an emcee, he has produced songs for several hip hop artists other than Jay-Z, including Group Home, M.O.P, Ras Kass, Rakim, Kool G Rap, and others.
