A little late on this one (it started last Sunday) but if you are looking for something fun to do on Sunday nights look no further than Reeves Park. Every other Sunday night through mid-August will feature live music at the park. Concerts start at 7pm and are free to the public. This year's Summer Music Festival is being sponsored by Phoenixville Federal Bank which has setup a website with additional information including the complete schedule.
