Ah Afro-Punk. Probably the most fun black people who aren't into "stereotypical" black music, dress, and culture will have all year. Last year I know a couple of bars held after events but I didn't find out about them until I was at the actual festival. People will also hand out flyers at the event. A coworker of mine, who is neither an "Afro" or a "Punk", ended up going to Do or Dine (which is a renowned, quirky restaurant that occasionally has DJs spinning in the back yard). Odds are that most of the bars where the Afro Punk crowd will end up afterwards is where a lot of this demo lives: Fort Greene, Clinton Hill, Bed Stuy, Prospect Heights and (probably) "East" Williamsburg or Bushwick. I know that answer was a bit open ended but each of these neighborhoods are in Brooklyn and fairly close to where the festival will be- Willamsburg and Bushwick being the furthest- and all of them have concentrated areas with bars. My personal preference would be Fort Greene along Fulton St, Myrtle Ave, and DeKalb Ave as they are all lined with restaurants and bars. A lot of the crowd in those areas is what I call "Vintage Clothes and Afros" because you'll see a lot of that.
