The performances of the Kharis Junandharu and Eki Tresnowening duo were typical because almost all of the folk genre songs they performed told stories about Surabaya. Starting from social problems, the atmosphere of the city, to the comfort women. The portrait of Surabaya on Silampukau songs is indeed not entirely sweet. They tried to portray the form of the City of Heroes as they were. The hustle and bustle of the streets, the localization of Dolly ( the Customer ), the traffic jam on Jalan Ahmad Yani ( Fall Night in Surabaya).
