Hideki Aoyama is a machine. His dad, Jun, was a well respected drummer, and Hideki plays pop with groups like the Jam Project and Momoiro Clover Z, but the first Babymetal concert you go to he just blows you away. I saw them at a festival several years ago so the no one had heard of them, but everyone talked about him after the show.
How he keeps up the pace for an entire show is beyond me.
