I've been playing in bands off & on since 1959, so.......
The most stable bands I've been in have *not* been democracies. They've been the vision of one person who's put it together & runs it as 'their baby'. Now, providing you're happy to to be the hired gun & pick up the money (& I am, mostly) this works just fine. Also, that kind of atmosphere makes it easier to say 'this is not working for me, I'll be moving on'.
I'm currently with a *very* democratic band and everyone can veto everyone else. This isn't terribly positive and at the end of the day we end up with a playlist by committee which is pretty bland, as no-one wants to stick their neck out and do anything a bit exciting.
The new female vocalist came in with a list of songs numbering about 12 which she *really* wanted to sing - the voting system has whittled this down to 1. Rather takes the enthusiasm away. I'm trying hard to extricate myself, but it will be seen as 'betrayal' and I don't want to leave bad vibes behind, but it looks like its inevitable.
