A grandma easily in her 70s left staff at the Coalition Drum Shop in La Crosse, Wis., with their jaw open after busting out some serious skills on the drum kit.

After the lady played for nearly a minute, she finished strong by telling the shop’s employee “That’s how it works, son.” You go, girl!

This was allegedly the lady’s first time playing double bass pedals. Check the video out below and let us know what you think.
