An unknown woman walked into the Coalition Drum Shop located in LaCrosse, Wisconsin and started rock out on one of the in-store drum set.
When employees spotted the "mystery grandma" jamming on the drums, they immediately began recording video.
According to the shop, they have no idea where she came from or what her name is.
Whoever she is, she should be the new spokesperson for the company.
Rock on granny, rock on!
