Arts preview: ProMusica Chamber Orchestra

Jim Fischer
Laurel Semerdjian

ProMusica Chamber Orchestra's creative approach to programming at the holidays includes the festive "Messiah" Side-by-Side Sing-Along on Friday, featuring local youth musicians alongside the chamber orchestra and an audience that doubles at the chorus.

The weekend continues with "Christmas Oratorio" at Worthington United Methodist Church (Saturday) and the Southern Theatre (Sunday). A slate of guest vocalists including Laurel Semerdjian (pictured) and the Lancaster Chorale will join the orchestra for works including the rarely performed yet seasonally-appropriate "Christmas Oratorio" by Camille Saint-Saens.
