Unisonic is the first studio full collaboration between Michael Kiske and Kai Hansen since Helloween's legendary albums Keeper Of The Seven Keys Part I and Keeper Of The Seven Keys Part II.

Mandy Meyer commented on the band's name: "There were so many ideas for a name and everybody liked Unisonic at the end. It fits to our band. United musicians from different backgrounds and countries".

Vocalist Michael Kiske (ex-Helloween), bassist Dennis Ward (Pink Cream 69) and drummer Kosta Zafiriou (ex-Pink Cream 69) worked together in the AOR project Place Vendome.
