Traditional Jodler Fest, Altstätten (St. Gallen)

A lot of traditional Swiss jodling and (alphorn) music:
How much more Traditionally Swiss would you need?

I see there's a traditional market, and many workshops to... also participate? It'll be fun!

As for the group, we'll be mainly expats, with hopefully an interest for the more traditional aspects of Switzerland, if not life. I should be able to help out with translating German if helpful :)
