There is a well-known song 'Bengawan Solo' composed by Mr. Gesang. In the central Javanese city of Solo, a statue of Gesang Martohartono looks over the gently flowing Bengawan Solo, or Solo River. It was the famous Indonesian singer-songwriter Gesang, who composed the celebrated Indonesian melody "Bengawan Solo" during World War II -- when the country was under Japanese occupation. The song describes the legendary river in a poetic and nostalgic way, that it is surrounded by mountains, its sources are near the city of Surakarta, that it ends in the sea, and that the merchant class always makes use of it. It is in the local Keroncong style, a popular folk style with influences from Portuguese. The Japanese, who occupied the country during World War II, brought the song with them to Japan after returning from the war. There, and also in the rest of Asia and later worldwide, the song became very famous.
