On one of the sweatiest nights of the summer, the heat did not stop an intimate crowd from jumping along to the angsty bops of Olivia Rodrigo’s new album and joining her in the shared pain of romantic love.

“You’re rocking out, I fucking love you!” Rodrigo yelled from the small stage.

The pop star announced the surprise concert Thursday morning, offering $25 tickets only to fans who arrived to Warsaw, a small Greenpoint, Brooklyn venue, in person starting at 10 A.M. The show comes after the June release of Rodrigo’s third studio album,You Seem Pretty Sad for a Girl So in Love, and marked the opportunity for Rodrigo to play some of her songs live for the first time and show off her chops ahead of her upcoming Daisy Chain Fields Festival in August and global Unraveled Tour.

By evening, the lucky ticket recipients stood shoulder to shoulder in the 1,100-capacity venue that resembles a high school auditorium and also sells pierogis off to the side, in keeping with its origins as a Polish cultural center.

The 15-song set list included a few old favorites, such as “driver’s license,” and “all-american bitch” as well as many songs from the soul-bearing new album, in which Rodrigo tracks the evolution of a romantic relationship, from the beginning highs to its demise. On stage, Rodrigo offered insights into her song-writing process.
