Fall Out Boy general Patrick Stump and one of Chi Towns finest link up together and create “This City”. Which will be featured on Patrick’s solo project Soul Punk.

Stump said

his relationship with the rapper goes back several years. “Before Food & Liquor came out he and I were talking about working on something together. I ended up producing the song ‘Little Weapon,’ for his The Cool record,” he said. “I actually wrote the hook for ‘This City’ with him in mind before I decided to use it for Soul Punk, so when the label asked me if I’d be interested in doing a remix with an MC he was the only real way I’d say yes.”
