Recent turbulent weather that triggered rounds of lightning and heavy rains — posing possible safety issues for music lovers — has prompted the rescheduling of some shows previously slated in the free 12th annual Concerts on the Green series at Kate Sessions Park. As a result, the following show has been rescheduled:
• Sept. 7 — The Siers Bros. (Allman Brothers, The Beatles, The Texas Tornados and their own originals).
The summer event is sponsored by the Concerts Committee and the Pacific Beach Community Foundation and runs from 4 to 6:30 p.m. Guests are invited to bring blankets, chairs, small umbrellas and picnic baskets (no alcoholic beverages) and plan to spend a Sunday afternoon in the park listening to music, dancing and meeting up with friends and neighbors.
