Capercaillie

Capercaillie are a Scottish folk band, founded in 1984 by Donald Shaw and led by Karen Matheson, and which performs traditional Gaelic and contemporary songs in English. The group adapts traditional Gaelic music and traditional lyrics with modern production techniques and instruments such as electric guitar and bass guitar, though rarely synthesizers or drum machines.

They have sold over a million albums world-wide, including "three silver and one gold album in the UK". The BBC notes that the band has "achieved enormous global success both as a group and as individual musicians."
