Voiceless Wagner in Redwood City

Do you secretly prefer Wagner's The Nibelung's Ring without singers, but would like something longer than the traditional concert chunks? The Redwood Symphony offers Lorin Maazel's "symphonic synthesis" of the whole Ring cycle: It's like an hour-long Richard Strauss tone poem, except it's by Wagner. Also on the program: Rachmaninov's almost equally epic Rhapsody on a Theme of Paganini, with pianist Daniel Glover. Eric Kujawsky conducts.
