I don't know what I think anymore...Baltimore and DC are obviously not the same.. but are they the same music market? that is the question....I tend to think what really matters is how do promoters see them.. do they view them as the same market? should they? On Pollstar when you search Washington DC you pull up the Baltimore shows too....
Last night I drove to Baltimore for the Rev and I made it in about 50 minutes from Arlington, VA...
I tend to think they are not the same market but that there is a little bit of overlap for smaller acts (if you don't have too many fans I guess sometimes you might have to only play one of them...playing one kind of means you can't play the other)... some big tours will hit both.. look at Stevie Nicks/pretenders. .they played Verizon earlier this month or last month and they're playing a show at Royal Farms early next year..
