Make Music New York

In celebration of the longest day of the year, musicians take to the streets, sidewalks and parks in all five boroughs for more than 1,000 free concerts in this massive festival. Highlights include the Blue Man Group doing a drum-off, a mobile Ella Fitzgerald piano bar and a program of celestial-inspired songs at the Museum of Natural History.
