SummerStage is turning 40, and to mark it, the festival is offering New Yorkers with $5,000 to spare the chance to bolt their name onto a VIP seat in its Central Park home. The pitch landed in an August 3 email from City Parks Foundation, the nonprofit that produces the free concert series.

Here’s the deal. A $5,000 contribution buys a personalized plaque on a seat in the Terrace lounge at the flagship Central Park venue. According to City Parks Foundation, the plaque can proclaim your love for SummerStage, honor a loved one, or mark a moment that matters to you. The gift is fully tax deductible, and the foundation says a limited number of seats remain.

The money is the point. SummerStage is free to attend, but not free to produce, and City Parks Foundation says every show depends on donors to keep it running. The organization frames the campaign as a way to secure the future of what it calls New York’s largest free outdoor performing arts festival, and to keep it free for future generations.
