His time slides up and down to be honest! Better than I am though!
That's one teeny tiny drum room!
it doesn't look like he's using earbuds, and certainly not using headphones.
this means he is listening through regular speakers to monitor what he's playing along to.
not sure if you've ever done this before, but listening and playing along at the same time with loud acoustic drums is very difficult without the use of an adequate monitoring system, either headphones or stage wedges. I'd say he nailed it, despite the song monitoring handicap.
