No, I have none done a Kickstarter per se, but I have done all of the same processes before there was Kickstarter. There are so many hats on my rack, but lets just say I am the manager of a multimillion dollar business, so I not be sptuid...

I have been an indie label, and have handled AP, AR, international shipping/receiving, contract generation and negotiation, artist management, recording, mixing, mastering, pressing, etc for PDC and others. I have sold and shipped over 40k units for PDC alone. So, 4k is not a big deal, if you are set up for it. Making the video is not a big deal. We shoot commercials, training and product review videos all the time at work. The only hurdle would be getting the music, the magic and the band to happen. No money or person can force that.
When soliciting a certain member to see if he would be interested, he said something that I should have thought of as an artist. It is totally understandable, given his age and experience. He said they would make it on their own,
if they were to make one (an album). He had no interest in playing under or on some other parties project. My Kickstarter proposition provided mixing and mastering by two household name guys, who are mixing HUGE artists. Petra would have benefited from the guys portfolios and industry clout. They would certainly have a better shot at another Grammy nomination than they do now. It only made sense (to me) to say, "Hey, we will remove the stress of production". I thought this would be better than saying, "Here is some money, go do ALL of the work". This particular person said he would not take direction from someone else. Totally understandable. Some artists would rather live and operate in their own abilities and circles of success. Nothing wrong with that. I get it.
