Cheap$kate: FREE events in NYC this weekend

Laura Marling, Michael Kiwanuka and Willy Mason at Celebrate Brooklyn!
Venture out and celebrate Brooklyn tonight with some international flavor from across the pond. British folk singer-songwriter Laura Marling and British soul singer Michael Kiwanuka will take the stage at the Prospect Park Bandshell, along with songwriter Willy Mason, as part of this year's FREE Celebrate Brooklyn! concert series. (Though it is FREE, there's a suggested donation of $3 at the door, so if you can afford the minimal fee, don't be a total Cheap$kate and fork it over.) Various artists will perform throughout the summer, so check the site to see if your fave musician will grace the Bandshell stage. (Thursday, 7-10 p.m., FREE, Prospect Park Bandshell, closest entrance at 9th St. and Prospect Park West, bricartsmedia.org)
