Yesterday marked the final *tear* JELLY pool party in Brooklyn for the 2009 season, and an unannounced Jay-Z came to help close down this summer's run of the popular Sunday series with wife Beyonce. Grizzly Bear, Beach House and Vega made the roster for the Williamsburg waterfront concert taking place against a beautiful sunset on the city backdrop, which was a huge improvement on the last show's sweaty, sunny swelter. The music fans filled the space, crowding up close to take in the music or lazily lounging on the field. After the show the rocked out band fans ventured to Brooklyn Bowl, for the traditional afterparty to the party. The free event drawing international recognition really did summer proud, and will be dearly missed until it takes the stage again, next year.
