In 2004, Kanye West was on tour with John Legend in London when Tim Westwood caught up with him backstage. There, Yeezy spit a freestyle including never before heard bars. You can watch it above. John Legend even joins him to sing a hook.

"John Legend, he taught me how to sing on this last tour was was on. We was doing vocal training right before we got on," says Kanye before jumping in to their singing exercises.

Later on in the video, he even spits a second verse. Be sure to watch the whole clip.

Kanye was hospitalized last week for a "psychiatric emergency," but seems to be doing "much better" now. He has cancelled the remaining dates of his Saint Pablo tour, but is expected to announce a second leg of the tour next year.

Plenty of people in hip-hop reacted to his hospitalization, including DJ Quik, 50 Cent, and John Legend himself. See what they had to say below.
