Hi-5 had been created in 2003 and consisted of Marlen Angelidou, Irini Psichrami, Frosso Papacharalambous, Shaya and Nancy Stergiopoulou, who were the winners of the Greek version of the popular talent show Popstars. The band released more than five chart-topping singles over the course of one year.
In 2003, their debut single "Ksero ti Zitaw" reached number one in Greece, on the strength of high sales. The single went Gold and enjoyed heavy radio and television airplay. Hi5 were able to sustain their commercial success by releasing the song "To Tixero Asteri" which also reached the top of the airplay charts, furthering the band's mainstream exposure. The success of those singles was accompanied by the release of Hi-5's debut self-titled studio album, which also reached number one in Greece, eventually reaching Platinum status for shipments of over 40,000 copies. The longevity of the album in the charts was supported by the commercial success of its third single, "Allo Agapi Ke Allo Sex". That single was able to replicate the success of the two previous singles, enjoying massive airplay thanks to the controversial and suggestive nature of its lyrics and the catchiness of its melody. By the end of the year, Hi5 received various awards from MAD channel and other shows because of their phenomenal success. In the Christmas season of 2003, the band also released a Christmas album, which was certified Gold partially thanks to the success of its single "Agnosto Paidi Tou Kosmou".
