A$AP Mob and Key just brought "Crazy Brazy" to The Late Show with Stephen Colbert.

It's easily the group's most elaborate television performance ever. Not only did the Mob from Harlem have the show's stage tricked out to resemble an unsettlingly eerie mental health facility, but the entire audience at the Ed Sullivan Theater were given hospital gowns, allowing for a great unexpected reveal once the camera panned out to the crowd. Knowing Mob leader A$AP Rocky, those straitjackets were likely designer as well.

"Crazy Brazy" is off the Mob's Cozy Tapes Vol. 1 and their performance coincides with next week's second annual Yams Day festival at New York's Madison Square Garden featuring the whole Mob, as well as Danny Brown, Joey Bada$$, Cam'Ron, Lil Uzi Vert and Flatbush Zombies.
