Before she explains the unique folk tradition of Gaali Geet from Mithila, Vibha Rani thinks it important to spell out the difference between gaali and its derivative. "Gaali Geet can be translated as teasing songs. They are not abusive," says the city-based writer, folk singer and theatre personality, who hails from north-eastern Bihar. This Sunday, she will familiarise Mumbaikars with her native region through a performance that amalgamates the oral and culinary cultures of Mithila.
