It sounds like a slow, moody interlude of an epic post-rock group like Explosions in the Sky or Not to Reason Why, but no—it’s the soundtrack to a 1921 silent film called ‘The Phantom Carriage,’ composed by 2013 Vintage High School grad Raja Orr. The film will screen with a live performance of this new composition from the pit orchestra, comprised of members of the Napa Valley Youth Symphony and conducted by Orr himself, on Saturday, Oct. 19, at the Jarvis Conservatory. 1711 Main St., Napa. 7pm. $15. 707.255.5445.
