Tonight’s free concert at Lubber Run Amphitheater will be cancelled due to the heat advisory, which has been extended until 10:00 p.m. on Thursday.

Potomac Harmony Chorus, and all-female a capella group, was scheduled to perform.

The decision to cancel was made in consultation with the group, both for their health and safety, and for that of the audience.

As of now, Friday’s performance by The U.S. Army Blues is still on for 8:00 p.m.
