This year, MMNY continues into the night with more than a dozen official After Dark locations throughout the five boroughts. Drop in to meet fellow MMNY participants, take a photo memento of the day at a pop up photo booth, catch a concert - from electronica in Gowanus to Bluegrass in Williamsburg - or make more music of your own at designated Open Mics, brought to you by Casio Keyboards.
