Founded in 1989 by Kai Hansen in Hamburg, Germany after leaving Helloween, Gamma Ray borrowed straight from the Helloween classics, and continued to pioneer Hansen's style of power metal. After four years with Helloween, Kai Hansen decided to leave the band at the height of their career. He then went on to do some studio work with Blind Guardian. Kai and his friend Ralf Scheepers from Tyran' Pace decided to start a project. They recruited bassist Uwe Wessel and drummer Mathias Burchard.
