Are most of these shows all found in big city's? I don't live in one so I really would not know. I think I want to try and find maybe a group, a good one that is playing where my oldest lives (Baltimore), can someone suggest where I could find out what or who would be playing in the state of MD?

Lucky for me I can use the computer and it has been how I have been finding out some of this stuff, besides email with family and some friends of course. Don't let it fool you young-ins, some older people still like to get out and do just the same as you, age is only a number remember. I'm just not exactly sure what I need to be searching for, a certain musician or just another search term I don't know about yet. Thanks in advance!

You sell things in a market, you bring a sick to a hospital, then you should perform to a where a big crowd is. I guess its easy to get a big crowd in a city rather than in a countryside. This is my just my opinion why these kind of performances are mostly being performed on big cities.
