Not a huge venue, but there's a campground down the Eastern Shore a ways where the owner hold a nightly campfire down on the rock beach, serves wild mussels, and waives the camping fee for anyone willing to play an instrument and lead some singing. And if the musician has a few CDs with him, he'll put them in the giftshop to sell. It's almost always fun, you meet other campers, hear some good music (usually). Wish other campgrounds would follow suit.
