The old saying "Don't judge a book by its cover" couldn't be more accurate here.
Looking at grandmother and drum instructor Dorothea Taylor, you definitely wouldn't be expecting her to break into an unbelieveable drumming cover of Disturbed's iconic 'Down With the Sickness'. But that's exactly what she does.
The video, which you can watch above, is not only entertaining though - it also carries an important message about the diversity of musicians.
"I've been drumming my whole life, and every one of these experiences has happened to me throughout my life," Taylor says in the clip. "Drummers come in all ages, sizes, shapes, ethnicities. And regardless of how good you are, how old you are, we're all still part of the drumming family,"
"So remember, don't judge a drummer — or anybody — by their looks. And always, always, always keep sharing your drumming passion to the world."
