For the uninitiated: a polyrhythm is a rhythm that pairs two or more different rhythms at once. Adam Neely does a great job of describing it, but the video can be summed up like this: His right hand hits the table with a rhythm of 11 equally spaced beats as his left hand beats it with seven equally spaced beats— this is a 7:11 polyrhythm, which is really fucking hard to make.

Does someone walk over and ask him to stop playing? No. Does anyone else rush over to pull out their own cell phone’s camera to film him? No. Does anyone in traffic honk at him while he plays his polyrhythm? No. But that’s probably part of the charm that makes this video so great. He’s just a lone man beating on a convenience store table with drumsticks to celebrate a national holiday.
