Kardinal Offishall

Canadian hip-hop players get no bigger than Kardinal Offishall (born Jason Harrow), whose rhyming talents, fanbase, and production skills are truly global. Just as comfortable behind the mixing desk as he is in front of the mic, Kardi possesses that golden touch. We begin here with a couple of high-profile hook-ups with his label boss, Akon — "Dangerous" and "Kill the Dance (Got Something for Ya)" — as well as the Rihanna collaboration "Rush," and key breakthrough track "On Wid da Show." Kardi keeps ringing the changes, and all the right bells, through our Next Steps.

Here, we begin to really understand just why Kardi stands head and shoulders above the Canadian hip-hop pack, as we trace a line from his major-label album debut — 2001's Quest for Fire: Firestarter, Vol. 1, featuring "Ol' Time Killin'" — to "Go Home With You" from 2008's Not 4 Sale: those leftfield vocal riffs on the latter track sound like nothing else out there. The ultra-chilled reggae stylings of "Maxine" and "Nina," meanwhile, pay homage to his Jamaican heritage.

Apparently, Ontario native Jason Harrow was inspired to change his stage moniker from KoolAid to Kardinal Offishall by the exploits of 17th-century French nobleman Cardinal Richelieu, scourge of the Three Musketeers — and with these Essentials he has successfully put to the sword all those who would challenge his position as Canada's ambassador of hip-hop. Our salute to the great K.O. takes in all aspects of his influence, from his standout contributions to "Northern Touch" by the Rascalz (also featuring Thrust, Choclair, and Checkmate), to his endlessly inventive production flourishes and his all-star teamwork with the likes of Snoop Dogg, Akon, will.i.am, Rihanna, and Bounty Killer.
