Rock and metal fans had to wait many many years 23 to be exact before it finally happened: German metal icons Kai Hansen and Michael Kiske, who kicked off German Metal trailblazers Helloweens international triumph with the two Keeper Of The Seven Keys records at the end of the 80s, got back together again. Again? Yes, again: Hansen quit Helloween in 1989 to found Gamma Ray while Kiske left four years later to attend to his solo projects. Even though the band already formed a year before Kai joined them but it was his involvement that made UNISONIC a so-called supergoup.
