With all the wonderful music currently available I seem to have overlooked, so far, the wonderful Capercaillie one of the best of the traditional Scottish folk bands. Hailing from Argyll, the band was founded in 1984 by Donald Shaw and led by the voice of Karen Matheson, a voice which is as clear and pure as the waters from a highland spring.
They performs traditional Gaelic and contemporary English songs. The group adapts traditional Gaelic music and traditional lyrics with modern production techniques and instruments such as electric guitar and bass guitar, although in recent years they have returned to a more traditional style and their repertoire includes music of the Celtic diaspora from Cape Breton to Galicia.
The final two videos here are from a broadcast of Radio Galega on Galician TV. The "Skye Waulking Song", is used in the Edexcel Music GCSE Specification from 2009 onwards. The song is in the world music section, and is used as a representation of traditional folk music combined with rock music.
