Given that he's a world-famous emcee from Chicago, you'd figure that Chance The Rapper would've crossed paths with The Windy City's most notable rap alum by now.

But Kanye West didn't have that pleasure until the two appeared on the same Made In America bill this weekend.

After their face-to-face rendezvous, Chance posted the following message along with his picture: "Anyone who knows me knows how big of a moment this was for me. I've been his biggest fan since 04 and I'm pretty sure I'm still his #1 fan."

Back in May, Chance took to Twitter in order to stem his city's violent streak.

He used the hashtag #SaveChicago while a grassroots campaign took to the streets with posters and banners that read #SAVECHICAGO.

The city saw 42 hours of peace and non-shootings, which Chance attributed to the launch of the campaign.

Here's a few of Chance's tweets clumped together:

"When I was in LA My pops asked me to help with a project. He was tryin to get Community Org's in CHI to prevent every murder on Memorial Day. He had talked to Churches, Schools, Outreach Prog's and Business's, trying to get them to commit to saving every life possible yesterday. The plan was to get these mass numbers of people out on street corners Friday night with posters and banners with the plea "#SAVECHICAGO." His plan was to get radio stations like @WGCI and @Power92Chicago to say "PUT YOUR GUNS DOWN CHICAGO" every hour on the hour the week before. All he asked of me was to say something on social media. And so I did ambiguously through tweets that hinted at an album, or a song #MAY23rd. And even though I was outta town I checked in constantly. Come to FIND OUT WE WENT 42 HOURS FROM THURSDAY TO SATURDAY NIGHT W/O ONE SHOOTING."
