What’s the opposite of a gritty African-American rap trio from Buffalo? How about a sweet Caucasian electro-pop singer-songwriter from Connecticut? Coincidentally (or not), that what you got from the late-night TV gods on Thursday. Who comes out on top? Well, my money is on the men of Griselda, who spat out their typically grim track Dr. Bird’s on The Tonight Show Starring Jimmy Fallon. But if you prefer the lighter touch of Chelsea Cutler’s Sad Tonight on Late Night With Seth Meyers, that’s OK too. After all, opposites attract and all, right?
