Stubete am See Ländler Orchestra

A friend of mine sent me this link about an orchestra of Swiss folk instruments (strings, clarinets, brass, accordeon, Schwyzeroergeli and hammered dulcimer) which was formed for the Stubete am See folk music festival in Zurich. The orchestra has music written for it, the Youtube link is to a piece by Dani Häusler called Waldstätter-Fantasy based ontraditional Swiss folk dances.
