Okie dokie, dwditty.

Jim Lad, what kind of music do you play? My sister has a bar in SL and she and her husband host live music there. I can talk to them about the possibility of hosting open mics if anyone is interested.

But you could do what you've described: "throw on a wee concert, anytime (you) want to" if you buy or rent some land and put up a venue of your own. If you do that, you can make the rules in your venue.
