yeah, i've caught mics and missed mics onstage, MANY times. And that's some quick reaction time on Stevie's part. On a mic that's 2 feet away. I can barely catch it when I'm singing on it. catching one that's 2 feet away, with stage volume full... at the bottom of its descent... and TURNING HIS HEAD to catch it in peripherals lol.
Even if they practice that, it's a one in hundred catch. Not even knowing it's falling? I'd bet it's an amazing prank, or more likely, they've cured a lot of the vision damage but it's just more profitable to sell him as a blind performer.
he's definitely over-selling the "look, i am blind, you can tell by how i swing my head around" in this video... nothing like his quick and precise catching of a mic stand 2 feet away at bottom of its fall at a live concert lol!
