Veteran US protest singer and activist David Rovics has written a terrific blog entry on organising fundraising gigs.
The problem for so many socially concerned / activist would-be promoters is that promoting is not their business, so they often don’t know how to make it work. There are a bunch of small details that need to be got right, organising any event. They also tend to be nicer, more heart and soul oriented people, than professional promoters, which isn’t always an advantage in event management!
Anyway these tips are a fantastic start, at least:
