It's rare to hear John Rutter's Mass of the Children performed in Pittsburgh. It's also rare that two of the city's top youth musical groups join forces to perform a major work.

That will happen this weekend when the Pittsburgh Youth Chorus will team up with Three Rivers Young Peoples Orchestras to present Mass of the Children. The performance is Sunday, April 14 at 4:00 PM at Moon Area High School. The Grove City College Concert Choir and Touring Choir will also join them.

Three Rivers Young Peoples Orchestras will join with Pittsburgh Youth Chorus to perform Rutter's "Mass of the Children"
