The 4th annual Make Music Philly has been announced for Tuesday, June 21st. The all-day, free event marks the longest day of the year with concerts throughout the city, encouraging musicians of all abilities, backgrounds and genres to get involved. Past years have featured pop-up performances on street corners, at subway stations and in the middle of scenic parks.

We’ve seen established acts like Lee Fields & The Expressions tear through Penn’s Landing, Opera singers serenade beer garden patrons and garage bands air out in Clark Park. If you would like to register as a performer for this year, please visit the Make Music Philly homepage here. Check out a highlight reel produced by Tri State Indie (and featuring a song by Toy Soldiers) below.
