K-Def was also member of the duo Real Live, who released one album The Turnaround: A Long Awaited Drama on Big Beat/Atlantic Records in 1996. "Real Live Shit (Remix)" featured Cappadonna, Ghostface Killah, Killa Sin and Lord Tariq.[2] During the 1990s, K-Def co-produced some of Marley Marl's tracks. K-Def is mostly known for his blues/soul sampling style. While the majority of his early-mid 1990s productions were produced using the Akai MPC sampler/sequencer, around 1997 he started incorporating the computer into his work flow, and now exclusively uses a software based setup. In 2004 K-Def produced "Its Over" on the Ghostface Killah release, The Pretty Toney Album (Def Jam). He then contributed tracks to another Ghostface project Theodore Unit, and Ol' Dirty Bastard's The Osirus Mixtape. He was a contributor to Diddy's 2006 release, Press Play, and in 2007 he produced a track on UGK’s album, Underground Kingz. In 2006, K-Def released an instrumental album called Willie Boo Boo The Fool. The album was originally only available on CD and vinyl, but was digitally re-released in 2008. In 2008, K-Def released a collaborative EP with the rapper Dacapo, under the name The Program, titled The Article.[3]
