Vic Mensa has performed with the Gorillaz on a handful of occasions. He handled Del the Funky Homosapien's duties on Gorillaz mega-hit "Clint Eastwood" during a 2014 performance at Governor's Ball. Shortly thereafter, he expressed a desire to get in the studio with Gorillaz mastermind Damon Albarn. It looks his wishes are being fulfilled.
Remi Kabaka, otherwise known as the voice of Gorillaz fictional drummer Russel Hobbs, posted an Instagram picture of someone who looks suspiciously like Vic Mensa in the studio last night. According to Reddit user u/JordanPowers95, Kabaka initially tagged Mensa then removed the tag, which would imply that the band is trying to keep the collaboration on the low.
Gorillaz began working on their new album last fall. They have previously collaborated with hip hop acts like De La Soul, Snoop Dogg, & MF Doom. Looks like Mensa may soon be added to that list.
