Yeah, in this electric age (heh) some people tend to forget about things like streetwork, flyers, billboards or ads and not everyone surfs the Internet in search of local gigs or follows what their favourite bands are up to. It's just weird that in some places the promotion seems to be working great, while elsewhere nobody knows the band is coming to town and the shows get cancelled. Money surely may be the issue too, but I imagine that most people will find a way to see such an amazing bill somehow, unless they're completely broke or have to choose between the gig and feeding their children.
