Unisonic is a German heavy metal/hard rock supergroup, founded in November 10, 2009 by former Helloween singer Michael Kiske alongside Dennis Ward and Kosta Zafiriou from Pink Cream 69. Mandy Meyer, formerly in Asia and Gotthard was soon added to the line-up, while in 2011 the band was joined by Gamma Ray leader and Helloween founder, Kai Hansen.
The band released the EP Ignition and their first studio album Unisonic in 2012. Unisonic is the first full studio collaboration between Kiske and Hansen since Helloween's seminal albums Keeper of the Seven Keys, Pt. I and Pt. II.
Vocalist Michael Kiske (ex-Helloween), bassist Dennis Ward (Pink Cream 69) and drummer Kosta Zafiriou (ex-Pink Cream 69) had already worked together in the AOR project Place Vendome. After the release of Place Vendome's second album, Streets of Fire in 2009, the aforementioned musicians decided to work together and form a new band. Dennis Ward suggested the recruitment of Swiss guitarist Mandy Meyer (Krokus). Unisonic began their first tour in June 2010, playing some warm-up shows in Germany and performing at Sweden Rock Festival  and Masters of Rock Festival in the Czech Republic as well.
In January 2012, the band released its first EP titled Ignition, through EarMusic (Edel AG), together with a video for the song Unisonic. The band's self-titled debut album was released on 30 March 2012 and entered several international music charts, scoring the highest points on the Finnish albums chart, Japanese albums chart, German albums chart and Swedish albums chart.
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".
Unisonic embarked on their first world tour in May 2012 playing in South America  and in various European music festivals, such as Masters of Rock, Hellfest, Rock Hard and Gods of Metal among others. The second half of the tour included concerts in Japan, Taiwan, Korea, Russia, Spain and Germany.
In April 2014 the band announced that their new EP, For The Kingdom, will be released in May 2014 and their second album on 25 July 2014. Unisonic also announced some tour dates for the summer festivals of Masters Of Rock, Leyendas del Rock, Skogsrojet and Bang Your Head.
