The concert itself takes place at 9 p.m. and will be followed by fireworks, weather permitting. This is a free community event and no tickets are required. There will be a live broadcast on WCLV and WCPN and the video will be live streamed on the orchestra's website. You'll find full details there, as well. (Niesel)
