Formed by Kai Hansen in 1990, Gamma Ray is one of power metal's most respected and influential bands. The quartet was originally a sideproject for
Kai Hansen and Ralf Scheepers, but eventually evolved into the quartet it is today. Though Gamma Ray's sound has evolved throughits eight albums,
the band has not generally written outside the perimeters of German power metal. Along with the likes of Helloween, BlindGuardian, Primal Fear, and
Running Wild, Gamma Ray forms the core of the German power metal movement.
