Downtown's Orpheum originally served as a silent movie house. Before its 1990s restoration, the Valley of the Sun Chapter of the American Theatre Organ Society raised funds to sponsor the installation of a huge Wurlitzer assembled from vintage parts. Occasions to hear this gorgeous monster in action are rare. One of our favorites is Silent Sundays, when a virtuoso organist plays accompaniment to an actual pre-talkie film. The acoustics are stunning, and many of the selections are the very same ones used by theater organists back when the films were released. (They kept notes.)
The screenings are sporadic at best (and the films VOTS-ATOS can afford to rent are sometimes a little weird), but the chapter accepts donations to help support the next Silent Sunday and hosts regular meetings and events featuring the Orpheum instrument and other great local organs, each one an entertainment experience like no other. So it's worth stalking the website.
