Burundi culture is based on local tradition and the influence of neighboring countries. Although prominent in cultural terms, it has been aggravated by civil disturbances. As agriculture is the main industry, a typical meal in Burundi is made up of sweet potatoes, corn and peas. Because of the costs, meat is eaten only a few times a month. When more close burnders meet together they drink impeke, a beer from a large container to symbolize the unity. Notable personalities include football referee Mohammed Tchité and singer Jean-Pierre Nimbona, popularly known as Kidumu.
