there's a good one at Bayreuth, apparently...
I heard that, too, tonybob. Don't they flog off any leftover tickets at half price at some point?
Seriously, though, that seems to be the one and only complete cycle this year. Weimar seems to be putting on all 4 parts but in a very odd sequence. I've never been to Weimar, though, so it's given me food for thought. Here's the list from operabase - not entirely comprehensive, I'm sure, but the best quick search utility I know of.
http://operabase.com/oplist.cgi?id=none&lang=en&is=Der+Ring+Des+Nibelungen&by=&loc=&stype=abs&sd=27&sm=1&sy=2008&etype=abs&ed=27&em=1&ey=2009I don't know anything about any of these productions, gladgrad , so I'm afraid I can't help with recommendations. Of course it's never a waste of money to visit a city like Gent or Dresden so perhaps you could just take pot luck. Both houses are well worth a visit.
