The European Fête de la Musique is being celebrated in New York this year for the first time—a day when music is coordinated everywhere, all over the city, all day on June 21st, the first day of summer and the longest day of the year. New York’s calling it “Make Music New York” and their website mentions that 300 cities are celebrating it worldwide this year (it was 100 last I read). http://www.makemusicny.org/?8ur&emc=ur
So, hey, Pittsburgh, it’s not too late. Grab your instrument and serenade your neighbors!
