Long time friends Lil Bibby and G Herbo have been taking their Chicago show on the road.
Last night, they brought some of that Chi-Town chaos to New Haven, Conn.
During their joint concert at Toad's Place, a man allegedly tried to snatch Bibby's chain.
This lead to a massive brawl which shut down the show.
Check out some footage of the incident.
You can't take Chicago anywhere.
