Very close to the Ramanathaswamy temple in Rameswaram we passed a large idol of Ganesha on a truck. Since we visited Rameswaram at the beginning of the Ganapati festival, this was not unusual. What made me stop was the drumming. A group of boys was ranked in front of the idol, wearing a white dhoti and a purple angravastram, playing a staccato rhythm on drums. It was loud, and the rhythm was not very complicated, but it was clearly the first act.
Behind them were older men with a yellow angavastram, with drums. I waited for them to start. It was a treat when they did. I discovered a wonderful new sound, made by rubbing the curved stick across the stretched membrane of the drum. Note the oldest man in the ensemble (at the center of the photo above, facing the camera). If the colour of the angavastram is anything to go by, then he was clearly special. He was absolutely focussed on the music, and seemed to be directing the others.
The drums are an announcement of an approaching event, and my guess was that this was merely the start. It would be some time before the truck moved, and the drummers would move behind it, announcing the approach of Ganesha.
