There isn't much of a scare factor in the Redwood Symphony's annual Halloween concert. It's a family-friendly event that features a “tour of the orchestra,” with all the instruments demonstrated. The pops concert that follows includes a piece drawn from an episode in Norton Juster's classic The Phantom Tollbooth, Mussorgsky's Night on Bald Mountain of Disney's Fantasia fame, and Gounod's Funeral March For a Marionette, known to listeners of a certain age as the theme from Alfred Hitchcock Presents.
