This is an absolutely blistering Roots assisted rendition of tUnE-yArDs, errr, tune “Gangsta” from their annoying to type album w h o k i l l. Jimmy Fallon has had a lot of great musical guests on his show, from Lykke Li to Odd Future, but this is definitely one of my favorite performances yet. Lead singer Merrill Garbus is mesmerizing, ?uestlove cool as ever and Black Thought spits a dope verse to add to this very much worth watching performance from Monday night. Hit the jump and check it out.
