Horslips - Dearg Doom

Arguably the first Celtic rock band was Horslips.

With St. Patrick's Day coming next week I thought it would be an ideal time for their song "Dearg Doom." 

Irish Gaelic for "Red Destroyer" is Dearg Doom, it refers to the mythological warrior Cu Chulainn. And "Dearg Doom" is a song from the Horslips concept album The Táin.
