A Patriot Day concert dedicated to those who lost their lives in the terrorist attacks Sept. 11, 2001, will be held on the 25th anniversary — Sept. 11 — in Cranberry Township.

The concert begins at 7:30 p.m. at Hope Lutheran Church, 8070 Rowan Road. Admission is free. Donations will be accepted.

The concert features classic organ music performed by Kathy Kemerer. It includes two works by composer Leo Sowerby: “Requiescat in Pace,” a somber piece created by Sowerby in 1920 in honor of lives lost in World War I; and “Fantasy for Trumpet and Organ” featuring Michael Derrico on trumpet.
