'Clo dubh Clo dunn' is a re-release from the Scottish Tradition Series and it features 18 traditional Gaelic singers and their songs, recorded by the School of Scottish Studies in the 1950s, with the addition of one or two recorded in the 60s, 70s and 90s. All are unaccompanied.

"Singling out a few of the many musical gems to be found on this set, mention must be made of the Angus Kenneth MacIver's version of 'I ri iu o ro leannain'. Recorded in 1969, Angus, from Uig, Lewis, sings in what has become known as the traditional Lewis style. The song is a beautiful love lament and he sings its verses and refrain with detailed ornamentation, piecing together the melody as though it were a mosaic of inflection, with drama and emphasis coming from the words. It gives a real insight into the old music of Lewis."...from a review in The Living Tradition  Folk Music Magazine
