Bob Delyn a'r Ebillion are a folk-rock group from Wales, singing both in Welsh and Breton.
Fronted by the Prifardd Twm Morys, Bob Delyn a'r Ebillion played a major part in the Welsh folk revival of the early 1990s.[citation needed] Their music combines an eclectic array of influences and instruments with more traditional Welsh folk and roots sounds; they were revolutionary within the Welsh-language music scene in doing this.
