This man is something of a whizz at Apple's drum kit on Garageband. That's an understatement, he's incredible at it.
Drumming is widely regarded as one of the hardest things to do extremely well but then miniaturising it and still being that good? Well that's just an achievement in its own right.
It's a testament to the iPad and to Garageband that the software is able to keep up with him.
