We're beaming proudly at the thought: What began as an harebrained idea in 2009 has blossomed into a festival set to make its return to the streets of Williamsburg and Greenpoint for a fourth year of music, film, art, ideas and more... and we do mean "more," as there are already some really exciting things in the works that we can't quite tell you about yet. Hang tight, though. Why don't you take a look here at some of this summer's highlights to hold you over? You might want to bookmark northsidefestival.com while you're at it, as that will become your one-stop source for all things Northside-related in the coming months. It'll be June before you know it.
