What it is. A live simulcast of the concert happening inside, projected onto the east façade and played through a sound system distributed across SoundScape Park. Not a recording, not a highlight reel — the performance, as it happens, with camera work built for the projection.
When. During the season, which runs broadly from October into April or May. WALLCASTs are scheduled on selected concert dates rather than weekly, so the schedule is the thing to check, not the season.
Cost. Free. No ticket, no registration.
How to do it properly. Bring a blanket; the lawn is grass and the park does not lay out seating. Some people bring low folding chairs and sit at the back so as not to block sightlines, which is the courteous arrangement. Arrive forty-five minutes early for a popular programme — the lawn area holds around a thousand and fills from the front.
What to expect from the weather. October and November evenings are warm and pleasant. January and February can genuinely be cool by Florida standards, and the park is open to the wind off the bay; bring a layer. Programmes can be affected by weather, so check on the day if the forecast is poor.
Food and drink. The park is city property and the usual park rules apply, so check the event listing rather than assuming. Lincoln Road is two minutes' walk for anything you need beforehand.
