Check his GBB wildcard entry for this year, titled "Star Sky." it's definitely him all the way. :) He also does this while driving... he's an uber driver, and it's still the same... he's just really talented, like Taras. And yes they're making the percussion sounds while singing. The devil's in the details... muscles, adam's apple... there's a lot going on there. Love Improver. And... Improver IS a soprano all the way, and if you check out he and Taras's tag team wildcard, where they used an iPhone and the iPhone mic to record it.. you'll see. There's a professional opera singer who did a reaction video to this, and he explained how everything is done. Seriously though.. Improver is very much a soprano. :)
