Mother Nature is making it hard on outdoor NYC concerts this year. But they're making do. This weekend is River to River Festival's two-day Ecstatic Summer 2013 held at Brookfield Place Plaza. However R2R just announced: "Due the high possibility of inclement weather, the Ecstatic Summer event has been moved inside to Brookfield Place Winter Garden." It's still free and open to the public. 5 PM start.

Today's event features Greg Saunier (Deerhoof), Seth Olinsky (Akron/Family), Reggie Pace (Bon Iver), Holly Herndon and more will be premiering new compositions performed by members of The National, yMusic, Plastic Ono Band and more. Part of the performance also features people playing ping pong as percussion. Could be very cool.

Meanwhile, today's 4Knots Fest at South Street Seaport is rain or shine.
