The Scottish music scene is a significant aspect of Scottish culture, with both traditional and modern influences. The most famous type of Scottish music is the bagpipes, a wind instrument consisting of one or more musical pipes which are fed continuously by a reservoir of air in a bag. The fiddle and accordion are also traditional Scottish instruments, heavily featured in Scottish country dance bands. Famous traditional musicians from recent times include Andy Stewart, the Corries and the contemporary Dougie MacLean. Modern Scottish pop music has produced many international bands including the Bay City Rollers, The Proclaimers, Deacon Blue, Texas, Franz Ferdinand and Travis, as well as individual artists such as Gerry Rafferty, and world-famous Gaelic groups such as Runrig and Capercaillie. These have been joined by Gaelic punk bands such as Oi Polloi who give an ancient culture a new voice.
