In 1990, in Koprivnica (Croatia), four highschool friends (Dado, Mali, Žika, Kosta) first formed "Overflow". In the same year, they released their first tape ("Through the Department Store") and had their first few gigs, which came out as a success. But, in some of the early days, Kosta (bass) was already replaced by Kondrad Mulvaj because he had to go serve in army.
