Clannad are best known for introducing the world to the haunting vocals of new age chanteuse Enya, but this family band from County Donegal has been one of the most celebrated acts from Ireland due to their ever-changing spectrum of musical styles. Since 1970, the group has blossomed from explorations of traditional folk to encompass rock, jazz, new age, and more. They're also one of few artists to take Gaelic singing to the world stage and are known for their extensive work in film and television.
