Cabaret at a Queens post office, hip-hop at a barber shop in the Bronx, an aqua-opus on the banks of the East River, and ukuleles en masse at the Union Square Green Market. 

It's the longest day of the year, and Make Music New York has invaded the city's stoops, plazas, parks, gardens and even cemeteries of New York City.

The annual event sponsors nearly 1,000 free concerts in public spaces throughout the five boroughs. So take a walk around an extra few blocks at lunch today, there's a good chance you'll catch a show.
