Pay attention, and show respect.
There are appropriate times, and there are inappropriate times, to showboat.
Rhythms change tempo, volume, and energy level; and the queues for those changes are sometimes visual. That's so that there aren't words, which might not be heard over a loud circle.
At other times, the rhythm or tempo changes are emphatically verbally communicated; that vocalization becomes are part of the performance.
Some of the rhythms that we play have long, empty spaces in which a drummer can add their brief flares and solo. Avoid monopolizing those spaces; allow the other drummers in the circle to have their "moments to shine".
This is especially important to drummers who have a long experience of playing solo for dancers. Long empty spaces need to be rare in solo performances, and so those drummers are used to filling the space during every measure. Playing with a group means that you must adjust your style.
