The Alpen Echos have performed at some of the biggest Festivals in North America. These include:

Kitchener-Waterloo Oktoberfest-Held in Canada in the heart of October, this is the biggest in North America. You need to experience it to believe it. Make sure to check out the Concordia Club
Leavenworth, WA Oktoberfest - Great German beer and entertainment. They always bring over a group from Germany.
Milwaukee Germanfest - Many venues with excellent bands from the area as well as from Germany and Austria.
Bethlehem Musikfest - An excellent sampling of eclectic music from all over. Several venues located throughout with just about every type and style of music represented.
Ft. Lauderdale Oktoberfest Held in a beautiful setting in Bubier Park along the inter-coastal waterway. Strong German/Austrian community in the South Florida Area.
Frankenmuth Bavarianfest Annual Bavarian Festival held on the Heritage grounds. Spans two weekends in June.
Fort Wayne German Fest Held in June, Great bands from the region and sometimes a band or two from Germany.
Jasper Strassenfest The biggest street party around. Held in Jasper Indiana on the Thru-Sun of the first Saturday in August. See you there.
Stone Mountain Alpen Fest No longer being held. To bad. Beautiful setting for an authentic Bavarian Oktoberfest.
AlpineHelen Oktoberfest Starting in September, this festival runs through the end of October! An Alpine Town set in the mountains of Georgia.
German Village Oktoberfest Columbus, Ohio. Was one of the top run Oktoberfests in the country. The entertainment was excellent and eclectic. Unfortunately the past few years they have been losing their German flavor. It has now become more of a Polka/Music Festival.
Oktoberfest Zinzinnati By far the biggest beer blast in the country.
Terre Haute Strassenfest Pitch a beer tent in front of the Indiana State University Dorms and you got yourself a party.
Schwaben Oktoberfest By far the most authentic "Old World" style Oktoberfest. Bands from Europe as well as the finest Dance Groups from the area. Add to that the home cooked foods, plethora of Imported beers and of course, plenty of Jaegermeister.
Space Coast Oktoberfest Melbourne, Florida. It's in Florida, do you need any other reason to go?
