The songs Alithina (Truly) and Arketa (Enough) from the CD Tis Nyhtas Oniro (Dream of the Night) became popular in the north, and as a result Kiamos' stock rose considerably.
In 2005, Kiamos appeared at Asteria, one of the most popular entertainment venues in Athens, with the initial 20 scheduled performances turning into 9 consecutive months (April–January).
In the summer of 2006, while still performing at Asteria, Kiamos signed a contract with Universal Music; his first collaboration with the label, Monima Erotevmenos, was released in June that year.
