Some promoters will never put in the groundwork to push a gig,or leave it the last minute. If I can't find anything about a gig I know is on I think that's a bad sign. They then seem suprised hardly any showed up.only so much a singleband can doo. Perhaps that's why sometimes at some gigs each band has its own audience that promptly leave,replaced by another one.
That is true in some cases but even if a promoter flogs themself stupid promoting a gig that's no guarantee these days.
Curse ye Facebook events and yer promises of great riches and bountiful wenches, when in reality all that transpires is a chap and his parrot and someone asleep at the back.
