“We Love Mozart and Bach” opens the 2019-2020 season of the Pennsylvania Sinfonia Orchestra, 7:30 p.m. Sept. 28, Christ Lutheran Church, Allentown.

A snowstorm canceled a Mozart program in March by the Sinfonia. Dr. Allan Birney, Music Director of the Pennsylvania Sinfonia Orchestra, programmed two pieces from that program and added a third piece by J. S. Bach for the season-opening concert.

The program includes Mozart’s “Symphony No. 17 in G,” K. 129; “Violin Concerto No. 4 in D,” K. 218, with violinist Rebecca Brown as soloist, and Bach’s solo cantata No. 82, “Ich habe genug,” with bass-baritone Anthony Sharp.

Brown has been principal second violin of the Sinfonia for more than 30 years. She performs in the Bach Festival Orchestra, Satori and Allentown Symphony Orchestra.

Sharp is a graduate of Temple University and is a chorister with Opera Philadelphia.

Tickets, at the door, Christ Lutheran Church, 1245 W. Hamilton St., Allentown; PASinfonia.org; 610 434-7811. Tickets for those 62 and older are available. Students are fee. A limited number of economy tickets for any age is available for seating in rear rows and must be ordered by phone by the Friday before the concert.
