Lol, that part of Switzerland is the only part I know, and yes I do love it. We traveled from Nuernberg to Ulm, passed the Bodensee, went through the western tip of Austria, then through Liechtenstein and Switzerland via Chur (where we overnighted), then south to Italy by Lake Como to Milan. Then toured Genoa, Pisa, Florence, Rome, Naples, Pompeii, Sorrento, then north again to Padua and Venice, across the Brenner Pass to Innsbruck, then back to Germany.
I discovered Cantus Firmus Surselva when looking through YouTube for the Mozart C minor Mass, and thought they were the best.
And I really got a kick out of these interviews.
