""Empire of the Undead" is a must buy for power metal fans, and an essential item for true Helloween fans. It is by far the most exciting and memorable release in years and continues the unbelievable run by German bands in 2014. All the ingredients are there, especially the youthful energy in the solos (thank you, Henjo Richter) and in Kai's voice. It may be an "acquired taste" for some, but I wouldn't have Kai sound any other way. He is pure metal and Gamma Ray's legacy at the power metal altar is complete".
