Unclean hippie ping
I especially like that guy who is very serious about clicking two sticks together, and the other guy kneeling with his tiny tambourine, and looking bored! What finesse. These people qualify as serious adults how? The only surprise is that they are wearing clothing and shoes instead of feathers and loincloths. More proof we are descending into Third World status.
All of the drums in this picture possess synthetic heads, not african goat skin. The guy with the sticks or claves is holding them wrong. The central drum is meant for two handed soloing, not as a bass drum beaten with a stick. The stick drum on the left is a Brazilian samba instrument, as are the small tamborines, and are not often seen in drum circles. This looks like a beginner circle.
A decent circle with several competent lead drummers will make you want to shake your bootie, depending on how repressed you like to keep your libido. You won’t find much beer can litter at a drum circle.
