There was no bands directly responsible, I have always been into folk music and metal although one band that I was listening to a lot at the time of Cruachans creation was an irish band from the 70's called The Horslips. Although they were just rock music, at the time they were as heavy as it got and they were all professional folk musicians who mixed Irish folk with rock, I still think they are a great band. I was listening to Sabbat and Skyclad at the time aswell as all the black metal stuff of the time.
