I've attended Kidstock every year with my kids and they thoroughly enjoy the show. While primarily there for the music, they like the atmosphere, the clowns (the National Circus Company), and between-act educational pieces from Port Washington's Bach to Rock.
This year's Kidstock features two returning acts and one newcomer – Alex and the Kaleidoscope, Joanie Leeds and the Nightlights, and the Dirty Sock Funtime Band. We're familiar with all these groups (and broken bread with one of them), so this is almost a homecoming.
Joanie Leeds is making her Kidstock debut but has appeared on Long Island before. This is a nice open setting (and good weather is expected), so turn out for this free concert experience. The press release is here if you need further information.
