I think it would be nice if each line up was different considering how many musicians are in town for such a limited time. Because I guarantee there are more than enough people coming to fill up every bill. But I've been given the distinct impression in the past that this is an unpopular sentiment. Nobody really seems to understand why I think this is a good idea.
Provided they dont fill up to an over stacked bill w/ not enough time for everyone to pay and those playing run longer than their given time limit. I'm all for lots of people playing.. provided people know what their time limit is, follow that and keep things moving smoothly. And who ever is putting on the event... should be willing to cut the PA should someone feel like taking more time than given.
