K-Os feat. Drake, "Faith" (2010)
K-Os' effortless blend of hip-hop beats, pop vocals and Caribbean cadences has made him one of the most influential Northern rap artists ever. Yet despite critical acclaim for albums like 2006's Atlantis: Hymns for Disco, he never broke through to the American mainstream. Still, you can hear clear similarities between K-Os and the Canadian rapper who truly cracked the U.S. market. "His father's American, and so he understands, he gets American culture," K-Os said in 2010. "It's an amazing thing to watch, and I hope people in our country take notes on how he's doing it." Drake and K-Os made several tracks together in late 2009, including the soulful blues of "Faith," but they've never been officially released.
