It's generally best to ignore superlatives when reading, or writing, stuff like this. Miss Black America - in many ways a superlative band - don't lend themselves to the usual crop of vacuum-headed PR platitudes.
They aren't the coolest band in the world*. They aren't the youngest. Or the sexiest*. Or the buzziest or the hippest or the most outrageous. Yeah, they're The Best Band in the Fucking World, but isn't everyone these days?
The superlatives that actually matter: Miss Black America are the most belligerent, obstinate, gutsy, resilient, spirited band you will come across. What they do actually matters.
