Why is everybody so down on starting a project?... Don't musicians start bands?
Nobody's down on it. Everybody who's done it has remarked on how hard it is, especially in the absence of actual gig incentives. I think you'll find very few musicians actually start bands. Most join bands already in progress, I think. And you kinda hamstrung yourself from the get-go by insisting it be an all-Craig's List undertaking.
It would be nice if that group could fund some gear.
Yes, you've been very clear on what you want out of it. The hard part is going to be convincing others that they should put in the work so you can buy gear. I come back to the question that you must be able to answer for anyone wanting to participate: "What's in it for me?"
If that makes this a vanity band, then it is a vanity band.
No, what makes it a vanity band is assembling a group of people to play music
you want to play, without providing any incentive to the players other than they should like it too. This is hard enough for BL's with hired-gun session players. Finding a group off the street who all share your vision and passion and want to do it only for the sheer joy of participation would be quite a coup.
Professional musicians will expect to be compensated. Hobby players have day jobs and family responsibilities that will trump anything you're offering, in the long run. You can get them together periodically for the joy of the music and the hang, but it's not going to be a priority without an incentive. "Make enough money for Remy to buy equipment" will likely not be perceived as a viable incentive -- even if in your mind it is for the benefit of the group. "What's good for Remy is good for us all." Won't fly for long unless you're recruiting starry-eyed naifs.
Music, remember? Language of the gods?
Yeah - got it. What's in it for the players? Set your sights on a goal, and get buy-in from the participants. You're a project manager - you know this. Book a gig with a date certain. A paying gig would be best, but if it's only a charity gig, so be it. We're a month away from Halloween which by all accounts is one of the big gig opportunities of the year. You should be able to score _some_ kind of party function for Halloween. You'll find out who's on board. If you _do_ score such a gig, somehow get video, and your press kit and website are on their way. Without something you can show clients, you're left with PowerPoints and finger puppets...
I'd be thrilled if you were able to pull this off.
I already work with people who are spring-loaded to dismiss anyone who points out risks and roadblocks as "not a team player" and are yet willing to throw those same people under the bus when adversity strikes saying "Why didn't you tell me?" You've got some challenges, not least of which are no clear goal to rally the troops and no incentive to put in the work.
