For the last seven years, on June 21 (the longest day of the year), New Yorkers have celebrated Make Music New York, a citywide event featuring free outdoor musical performances (and some indoor ones at night). There will be more than 1,000 this year, which can make it seem daunting (browse the full schedule here), but we spoke to the organizers of 11 events in Brooklyn about what they’re planning. There’s a diversity of styles (opera, choral, experimental, punk, toy instruments, folk, electronic and everything in between) being performed in a diversity of neighborhoods (DUMBO, Clinton Hill, Fort Greene, Crown Heights, Gowanus, Williamsburg, Bushwick and more). Go see something! If you’re not going to make music, you could at least listen. [photo]
