Even in the midst of a recession, it's amazing how there's always a surfeit of free shows in New York City... and Brooklyn in particular. While there's usually plenty to do in the borough proper, next weekend's Citysol festival in Stuyvesant Cove Park (adjacent to the East River and Stuyvesant Town) features many talents in the namer of a very pertinent cause -- urban sustainability. All acts will be performing in a solar-powered tent, while you can enjoy discounted drinks if you bring your own cup. Among the Brooklyn talents trekking across the river for the musical portion of the program on July 12th are the So So Glos (whose patented punk will go down favorably in what are sure to be humid conditions), Fiasco, electro fiends Love Like Deloreans (in what will be their homecoming apperance after a long tour), Shilipa Ray and Her Happy Hookers, and agitprop hip-hop duo Dead Prez (who are actually from Tallahassee but play here often enough that they may as well be native sons).
