Most definitely a group effect with you as the lynchpin! I'm sure the 3rd will go really well.
I've found the comments on promotion in this thread very interesting. When I started putting on gigs ten years ago, the internet wasn't really available as a promotional tool. As a rule, turnouts were much higher than they are now. I am absolutely sure that the hard copy flyers/posters that were all we had in those days reached far less people than event invitations on facebook/myspace/internet forum gig spamming/mass texts and emails do now. I have also frequently distributed 300 flyers for a gig with an eventual turnout of 30 people I know personally. In some cases promotion is done very poorly, but more and more often, promoters do a good job, people know about the gig and still choose not to go.
Why is this? A wider variety of entertainment available at home, including pirated downloads of music and films? Less and less desire for face to face contact, fuelled by internet forums, online gaming and live sex chatrooms? Late opening and drinks offers in pubs without a music licence? In the UK, gigs are linked with drinking heavily, chatting to your mates, being seen by the cool kids and going on the pull. Bands frequently complain about audiences only watching their mates or the headliners, and arriving late, leaving early or talking through all the other bands. I know bands who have played in Europe who talk about very different, much more respectful and interested audiences, and I'd be interested to see if turnouts have fallen as much in say, Holland, as we perceive them to have done here. If so, is this because gigs perform more of a social and less of an artistic function in Britain?
