"Ol' Time Killin'" is a hip-hop song by Kardinal Offishall featuring Jully Black, Allistair, IRS, and Wio-K, released in 2001.

[1] One day after performing at a club in New York City, Kardinal was in his hotel room talking to Saukrates, when he heard an infectious beat coming from downstairs.

Saukrates told him that Mr. Attic of Da Grassroots was playing beats in his room, then Kardinal went downstairs to check it out.

'[2]The featured rappers, Wio-K and IRS (Korry Deez and Black Cat) from Scarborough's Monolith crew, were chosen by Kardinal, because he used to hang out with them, and musically, they shared the same level of energy.

[2] After the video was released, many people in the hip hop industry became a fan of Kardinal, including Pharrell Williams, Clipse, and Pete Rock.
