Penguin Prison + Wild Yaks + Janka Nabay and the Bubu Gang + Monogold

Though it doesn't quite live up to the "leaked" version that a savvy photoshopper conconcted—the hypothetical lineup included free shows by the Strokes, Odd Future and many others—Jelly's Rock Beach lineup is still plenty good. It kicks off today with electropop maven Penguin Prison, colorful indie rockers Wild Yaks, never-stops-gigging Afropopper Janka Nabay and more. Party busses ($20) take off from Brooklyn and Manhattan at 1pm, so check for stops.
