Mostly Music in the Park

***August 6th's Mostly Music in the Park Concert at Mercerdale Park featuring Prom Date Mixtape has been canceled due to poor air quality.

We'll see you next week, Thursday, August 13, for the next Mostly Music in the Park featuring Mr. Pink!

The health and safety of our community, performers, and staff is our top priority. While air quality is expected to improve slightly throughout the day, it is forecasted to remain at or above unhealthy levels.

Thank you for your understanding. We will be exploring opportunities to reschedule this performance for later this month.***
