The nonprofit group behind the SummerStage concerts has canceled a scheduled Central Park performance by the popular R&B singer Kehlani under pressure from the administration of Mayor Eric Adams.

The move came on Monday after a top New York City official warned the group, the City Parks Foundation, that its license to stage the long-running concert series could be at risk if it did not “promptly take steps” to address “security concerns” raised by the planned show.

Billed as “Pride With Kehlani,” the concert was to take place on June 26 as part of the city’s broader Pride festivities. It was the second scheduled Kehlani performance to be canceled in recent weeks amid a furor over the singer’s pro-Palestinian stance.

Unlike Cornell University officials, who explicitly cited what they said were Kehlani’s antisemitic and anti-Israel views when they dropped the singer two weeks ago as the headliner of an annual campus concert, the city official, First Deputy Mayor Randy M. Mastro, did not invoke her personal opinions.

Instead, he said in a letter to the foundation’s executive director, Heather Lubov, that the Adams administration’s concerns were based on “the controversy” surrounding the scheduled Cornell performance, as well as the security demands posed by such an event in Central Park and by other Pride events around the city.

Mr. Mastro wrote that the police would conduct a security assessment of the concert. If the department determined that the event posed “an unacceptable risk to public safety,” he added, there could be implications for SummerStage’s future. The series began in 1986.
