It's not hard to fathom that Kendrick Lamar and J. Cole would get on a song together, even after the friendly jabs thrown between the two. After all, Kendrick was the only rap feature on J. Cole's last album, Born Sinner. It was even rumored that the two were going to release a collaborative mix-tape. Whenever two great rappers get on one track the competitiveness forces the two to rap at their best level. Sons of Liberty has the two MC's spitting god-like bars and letting the entire hip-hop community know that they can't be stopped. Will we see a collab from K.Dot and Cole anytime soon? Who knows, but for now enjoy this rare live performance of an unreleased song called "Shock the World" from their rumored mixtape.
