Brooklyn County Fair: The Hollows + Gangstagrass + The Newton Gang + Roosevelt Dime

You are, of course, aware that Brooklyn has a burgeoning bluegrass and ol'-fashioned country scene, right? Sample the local talent tonight at the Bell House: The Hollows top the bill with their rustic, rock-spiced folk, and then there's Gangstagrass, which, yes, does what you think they do: mix bluegrass with gangsta rap—and their recent album (featuring Kool Keith, no less) is called…wait for it…Rappalachia.
