Make Music New York turned 20 this summer, and it marked the milestone the only way it knows how: by flooding parks, plazas, sidewalks and subway overpasses across all five boroughs with free public music for a single day on June 21. In Bushwick, that meant a Latin jazz set, a cookout and homemade ice cream inside a community garden.

The festival, first reported by AMNY, is New York’s edition of the global Make Music Day now held in more than 120 countries. It ran from 10 a.m. to 10 p.m. on the summer solstice. Every performance was free to watch, and playing was open to anyone who wanted to sign up. The New York concerts were among roughly 1,000 performances statewide that Make Music New York helps organize each year.

Here is the part that separates it from a normal concert series: nobody curates the lineup. Make Music New York signs up musicians and host venues, matches them, and handles the city permits so performers only have to show up and play.
