In 2009, Charles Hamilton was an up and coming star and Kendrick Lamar went by K-Dot.
Kendrick had achieved some success at the point. He had a few mixtapes, and had appeared in the video for J. Rock's debut track "All My Life (In the Ghetto).'
Still, when he stepped up to the cypher at a Charles Hamilton event, Hamilton had to ask him his name.
See what happens next.
Could you tell from that early freestyle that Kendrick was going to be huge?
