 The Welsh traditional and folk music scene is in resurgence with performers and bands such as Carreg Lafar, Fernhill, Siân James and the Hennessys.The earliest surviving Welsh plays are two medieval miracle plays, "Y Tri Brenin o Gwlen" ("The three Kings from Cologne") and "Y Dioddefaint a'r Atgyfodiad" ("The Passion and the Resurrection").A recognised Welsh tradition of theatre emerged during the 18th century, in the form of an interlude, a metrical play performed at fairs and markets.
