The Griffin Rock robot band is a three-piece musical group which supplies music for functions in Griffin Rock. It includes a keyboard, drum, and something that resembles bellows.
The robot band was waiting at the train station at the Griffin Rock end of the link to the mainland, and started playing as the Griffin Rock Express approached. They abruptly stopped again when the train failed to stop at the station.
Their services were also utilized at the dedication for the Mayor Luskey Clock Tower.
