Guardians Of Mankind is a Finnish Gamma Ray cover band. They have recorded a Finnish translation of Valley of the Kings called Kuninkaidenlaakso. Gamma Ray themselves liked the Guardians' covers so much that they asked Kasperi Heikkinen from the band to replace Henjo Richter on some Gamma Ray gigs in Scandinavia when he hurt his hand and was unable to play.
