According to Toro y Moi and Das Racist, this weekend's free Afro-Punk festival is unfortunately cancelled due to Hurricane Irene. That said, as of this post, the festival itself hasn't said a word about it.
UPDATE, it's official:
The City of New York has rescinded all event permits for Saturday, August 27th and Sunday, August 28th because of the impending Hurricane Irene. The Afro-punk festival has been barred from holding any public assembly in Commodore Barry Park this weekend. Afro-punk staff have been meeting with officials and sponsors to try and avoid cancellation but have had to cancel this weekend's festival due to safety concerns. The event organizers are regrouping to plan the next steps and will keep the public updated.---
